Here are some more details about how to reproduce (I have only asked some clarifications on IRC, I haven't tried to reproduce this) 1. start a linux guest 2. connect to it with spicec on a linux client 3. switch to a VT in the guest by pressing Ctrl+Alt+Fn (press Alt for a few seconds so that it sticks, and then press Ctrl+Fn) Result: x.org on the guest segfaults Expected result: no segfaults I'm seeing the same problem on RHEL 6.3 + latest errata on x86_64. After booting up the guest and switching to a console X starts crashing constantly. I'll attach Xorg.log with the xorg nevr's appended. Thanks. Created attachment 611471 [details]

Created attachment 530071 [details] Xorg.log Description of problem: Xorg server crashes when switching to console by Ctrl+Alt+Fn shortcut on i386 guest. It does occur always when doing the switching first time after boot, after crash It does not occur on all guests always. Xorg.log in attachment. We had this problem some time ago and It was fixed that's why I consider it to be regression.

Connect with spice client to a Linux guest after booting the guest 2. Press Ctrl+Alt+Fn to switch into console. Actual results: Segfault Expected results: No segfault Additional info: On x86_64 I am not able to reproduce so far.
