Can you do debuginfo-install libvirt and then capture a trace with GDB. If you're not familiar with GDB, the following will hopefully do the job $ gdb /usr/sbin/libvirtd /var/cache/abrt/ccpp-1270793886-1686.new/coredump (gdb) thread apply all backtrace

This backtrace looks messed up, not really sure what to do to fix it. Can you reliably reproduce with the latest packages in F13? If so, please either paste the backtrace that abrt shows you, or as root run the following: 1) service libvirtd stop 2) gdb libvirtd 3) At gdb prompt, type 'run' 4) Reproduce the issue in another terminal 5) At gdb prompt, type 'thread apply all bt' I'm assuming this isn't reliably reproducable, so closing as WORKSFORME. Please reopen with the above info if you are still seeing this.
