Bug 547365

abrt 1.0.0 detected a crash.

How to reproduce
-----
1. Reboot, start virt-manager
2. Start 2 vm's at the "same" time by selecting the vm and clicking the start icon in virt-manager main window
3. Start another vm by double clicking on the name, followed by clicking on run from the new window.

After a fresh reboot I started virt-manager, fired up 2 more virtual machines for some testing. I then started one more virtual machine, and virt-manager segfaulted after I clicked on run (I double clicked the machine name, and clicked run in the new window). This is the log file from the crash:
Dec 14 14:34:07 buffy kernel: device vnet3 entered promiscuous mode
Dec 14 14:34:07 buffy kernel: virbr0: topology change detected, propagating
Dec 14 14:34:07 buffy kernel: virbr0: port 4(vnet3) entering forwarding state
Dec 14 14:34:07 buffy NetworkManager: <WARN>  device_creator(): /sys/devices/virtual/net/vnet3: couldn't determine device driver; ignoring...

Last logs from the machine log in /var/log/libvirt/qemu is:
LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin QEMU_AUDIO_DRV=none /usr/bin/qemu-kvm -S -M pc -m 256 -smp 1 -name rhel5-node1 -uuid 667d44b6-1683-a1a0-c195-453676b1ad39 -monitor unix:/var/lib/libvirt/qemu/rhel5-node1.monitor,server,nowait -boot c -drive file=/dev/vg_raid/lv_rhel5-node1,if=ide,index=0,boot=on -net nic,macaddr=54:52:00:76:48:da,vlan=0,name=nic.0 -net tap,fd=19,vlan=0,name=tap.0 -serial pty -parallel none -usb -vnc 127.0.0.1:3 -vga cirrus 
char device redirected to /dev/pts/15

After starting virt-manager again all vm's are still running but the machine started last, that one kernel-oopsed. If I double click the machine started last to open a new window and force shutdown that machine from that new window virt-manager crashes again. After that things seem to be back to normal, and the vm starts again from clicking start in it's own window. Virt-manager doesn't crash anymore.

I'm afraid I've not been able to repeat this so far...
