<font face="Verdana">I am still seeing this issue ( version </font>r46388
)<br>
<br>
It is tied to 3D somehow. Disabling it the issue goes away.<br>
Host = Ubuntu 12.04LT guest = any with 3D but I normally use Debian
based or OEL guests<br>
Host graphics = nVidia<br>
<br>
How to produce:<br>
start the guest (3D enabled) click on the device tab and then click
the CD/DVD and the guest aborts immediately.<br>
It does not even write back to the guest .vbox.<br>

that and you can attach a CD from within the guest. You can
also leave 3D enabled and simply log out and attach the CD from
the login screen.<br>

VBox lightdm-greeter?<br>

make no difference if the GAs are installed or not.<br>

All that is needed to trigger this segfault is to select

This happens on two separate (Debian based) systems the

It happens the second I click on select CD in the device menu.
I must admit that I am not the sharpest knife in the drawer with core
dumps. The dump is 7MB tar'ed (217.5MB) each.
I can send it to you if you like.

<pre wrap="">The core won't help me much since you're running your own builds, and I
wouldn't have the matching debug info.
Did you install the ...-dbg package? Then you should get much more out
of gdb than just some hex values.

<pre wrap="">How about enabling core dumps and looking where it crashes? I tried a
few CD unmount/mount combinations, and couldn't trigger any problems,
neither in VBoxSVC nor in the GUI.
