Bug Description

Binary package hint: xorg

Starting skype from the command-line causes Xorg to immediately crash & exit on this machine. In more detail, it seems like any GUI IO on the skype application is actually what causes the crash, as it is sometimes possible for gnome-session to start the app at login time, and the status bar icon shows the successful connection attempts; however moving the mouse pointer over that icon (this should generate a popup notification from the app) causes a crash.

When starting from the command-line the new window is focused, which seems to be enough to trigger the crash.

This is not skype-specific, I noticed similar behaviour from Opera (but have not experimented with reproducing this yet).

apport didn't seem to record skype as a problem application, so I've attached a gdb session of Xorg.

I am also experiencing what appears to be the same issue, however not only with Skype and Opera, but also with MusicBrainz Picard, VLC and VirtualBox (non-OSE).

If I launch VLC from the command line with cvlc, the video opens in a window with no sound, but launching standard vlc crashes, apparently when you move the mouse over the VLC GUI. Similarly, I can open VirtualBox, but as soon as I mouse over its GUI the system crashes.

Every time the system crashes, I get kicked back to the GDM login screen.

If there are any logs that would help out, let me know and I'll dig them up.
