Virtualbox 4.0 crash when clicking the "Settings" button -> Fixed in SVN

Reported by: Arthur Titeica Owned by:
Component: other Version: VirtualBox 4.0.0
Keywords: Cc:
Guest type: Windows Host type: Linux


Virtualbox 4.0.0-69151~Ubuntu~maverick The host is Ubuntu 10.10 x64 and the guest is Windows XP Pro SP3.

With the VM powered off when I click the Settings button the Virtualbox GUI dissapears and core is dumped.

I had installed all the four 4.0 betas and I didn't notice this problem so far. (I don't check settings that much though)

I'm attaching the log and the core.

The core dump is too big to be attached here. You may download it from

I have this problem too, with exactly same hardware and versions of host/guest.

in reply to:  description comment:3 by botio, 14 years ago

Same here, on a debian host, crashes on opening settings for every kind of guests.

comment:4 by Mohammed Berdai, 14 years ago

Same here on Fedora 14 x64.

in reply to:  description comment:5 by gesantkunstwerk, 14 years ago

I remember reading somewhere that its possible to change some of the settings from within the running guest (change memory allocation if i remember correctly) - does anybody know of a way to add usb or shared folders from within run running guest? I feel like it should be possible

comment:6 by gesantkunstwerk, 14 years ago

Maybe done through vboxmanage command? ? (sorry if i shouldn't be posting a workaround here)

comment:7 by gesantkunstwerk, 14 years ago

VBoxManage modifyvm --uartmode<1-N> <devicename>

I"ll stop now...

See more cases in this threads:

For me its crashing on Suse 11.3 / 64 with KDE 4.5x.

Seems to be on KDE Desktop. On Gnome it works for me.

i have new input on this bug

for kubuntu 10.10 x86_64

when 'details' is select (top right) on manager dialog box and then settings is clicked the app with crash each time

however if i select 'snapshots' (top right) then settings, i don't not get a crash

comment:10 by Sebastian, 14 years ago

See also #7909. Probably duplicate.

Same problem here: kUbuntu 10.10 x64

I can open settings when clicking a title (e.g. General or Storage) on the right side of the VB Manager while VM is powered off. Setting dialog opens as usual and changes can be made.

comment:12 by Sebastian, 14 years ago

Hi, great!

At least sometimes/for some vms, it works by clicking general; for others, it works when selecting snapshots (see comment 9), then the button.

I tried some more debugging; unfortunately, it crashes deep inside the (optimised) qt libraries, in inline code, so I'm unable to examine all data ...

@Oracle: Is the cause of the problem known, or should we investigate further? Maybe we should gather the QT versions we are using, here, to find out whether it is a qt version problem ...

Are there also i386-users who have this problem?

  • System: Opensuse 11.3 x64
  • Qt: libqt4-4.6.3-8.3.x86_64 from openbuildservice, not the opensuse original one


comment:13 by Frank Mehnert, 14 years ago

The cause is unknown but nevertheless I hope we can fix the problem quite soon.

comment:14 by Frank Mehnert, 14 years ago

Unfortunately still unable to reproduce. roentgen, could you attach the compressed output of dpkg --get-selections? Thank you!

by Arthur Titeica, 14 years ago

Attachment: dpkg.list.gz added

dpkg --get-selections

comment:15 by Frank Mehnert, 14 years ago

Thanks. All: Does this crash only happen for 64-bit hosts or for 32-bit hosts as well?

comment:16 by Frank Mehnert, 14 years ago

Now we were able to reproduce it the first time. Changing the widget style from Default (Oxygen) to another style prevents the crash here.

comment:17 by Sebastian, 14 years ago

Mh. I tried various window decorations and various desktop designs ... still same results ..

Glassified+Redmond, looks awful, still crashes ...

Sorry, Sebastian

comment:18 by Frank Mehnert, 14 years ago

Widget style please, not Windows decorations.

comment:19 by Frank Mehnert, 14 years ago

We were able to reproduce the crash and hopefully fixed it properly. I've created some test builds, you can download them here (openSUSE 11.3 32 bit, 64 bit; Ubuntu 10.10 32 bit, 64 bit). Could you check if the crash is gone?

comment:20 by Sebastian, 14 years ago

Yeah, Great, Crash is Gone!

Btw, I switched "Erscheinungsbild von Anwendungen", "Stil" from Oxygen to anything else ... VBox still used Oxygen and still crashed. Strange, but doesn't matter any longer.

Thanks, Sebastian

Thanks for the reports and the testing. Fixed in the next minor release.

comment:22 by dflogeras, 14 years ago

Could you tell me the rev number? I am interested in backporting this fix and I cannot seem to find it in the public SVN trunk. The last checkin there is a couple days before this bug was marked fixed.

comment:23 by Stefan Becker, 14 years ago

Testbuild checked with Opensuse 11.3 and it works now.

comment:24 by Stefan Becker, 14 years ago

And checked on Linux Mint (like Ubuntu 10.10). Same, working OK now.

comment:25 by Frank Mehnert, 14 years ago

Resolution: fixed
