segfault in libQt5Gui.so.5.6.0 from VirtualBox-5.1-5.1.0_BETA1_107766_fedora22-1.x86_64.rpm

[George R. Goffe]

I have just upgraded VirtualBox to the beta version (VirtualBox-5.1-5.1.0_BETA1_107766_fedora22-1.x86_64.rpm). I attempted to start VirtualBox but am getting a segfault in libQt5Gui.so.5.6.0. I'm not sure just who should look at this problem. Oracle (VirtualBox), the libQt people, or Fedora. This system is Fedora 23 at the "latest" upgrade level as of a few minutes ago

There is an open bug report on the bugzilla.redhat.com web site:

Bug 1342694 - segfault in libQt5Gui.so.5.6.0 running BETA VirtualBox

[johnlee]

think you are supposed to use the beta site for reporting beta issues.j

[George R. Goffe]

John,

Thank you for your update.

Do you have the URL for the Beta bug reporting web site? Please. I would like to suggest that this URL be added to https://www.virtualbox.org/wiki/Bugtracker

THANKS for your help,

George...

[Frank Mehnert]

Not sure if another link on https://www.virtualbox.org/wiki/Bugtracker would help. The announcements clearly state the the ​Beta/RC feedback forum should be used for reporting problems.

But thanks for reporting the problem anyway. This is a stupid problem which we didn't notice before actually changing the version to contain the string "Beta". It will be fixed with the next Beta of course.
