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):

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.

Additional info:
The command line is:

I had the same problem and filed this bug against abrt:
Bug 861844 - Backtrace parsing failed for . ... 11:0: "Thread" header expected
Comment 2 Cole Robinson 2012-10-05 09:57:13 EDT
Looks like that code is in spice, reassigning for further triage.
Comment 3 Fedora Admin XMLRPC Client 2012-10-15 02:12:48 EDT
This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.
Comment 4 David Jaša 2013-01-04 05:40:50 EST
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.
Comment 5 David Jaša 2013-05-03 04:47:15 EDT
James, Steve, could you retest on F18 to verify if the problem is indeed gone, please?

Thank you very much.
Comment 6 Jerry James 2013-05-03 10:00:26 EDT
I have used the virt-manager + spice framework heavily on F18 for the last few months, and have not encountered this problem.  Thanks!
Comment 7 David Jaša 2013-05-03 10:03:47 EDT
Thank you for testing!
