Created attachment 608006 [details] Backtrace generated by abrt, which it fails to parse Description of problem: I have a Fedora 18 x86_64 VM running on a Fedora 17 x86_64 host. I use spice to display the guest. Today, after installing the latest updates from updates-testing on the guest, I did some other work on the host for awhile. When I came back, the screensaver was on. I exited the screensaver, got just a quick glimpse of the guest's desktop, and this crash happened. I should really just turn off the screensaver in the guest, but then I wouldn't have found this problem. I cannot report this with abrt, because of this error: --- Running analyze_LocalGDB --- Analyzing coredump 'coredump' All debuginfo files are available Generating backtrace Backtrace is generated and saved, 10779 bytes Backtrace parsing failed for . 26:0: "Thread" header expected Version-Release number of selected component (if applicable): qemu-system-x86-1.0.1-1.fc17.x86_64 How reproducible: Always (or at least, it happened on 2 out of 2 attempts just now). Steps to Reproduce: 1. Create a Fedora 18 machine, with all updates from updates-testing applied 2. Display the machine on a Fedora 17 host with spice 3. Wait for the guest's screensaver to kick in 4. Type the user's password to exit the screensaver. Actual results: Qemu-kvm crashes. Expected results: Qemu-kvm stays up.

Looks like that code is in spice, reassigning for further triage.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
this line: > validate_surface: panic !worker->surfaces[surface_id].context.canvas suggests that this is the same as RHEL bug 824384, fixed in spice-0.12 that is included in Fedora 18 - so this could be closed as NEXTRELEASE or UPSTREAM in my opinion.
James, Steve, could you retest on F18 to verify if the problem is indeed gone, please? Thank you very much.
I have used the virt-manager + spice framework heavily on F18 for the last few months, and have not encountered this problem. Thanks!
Thank you for testing!
