Hi,
I've been tring to use QEMU-1.5.0 and Libvirt-1.1.0 to run a VM, but this problem comes up. The VM's log by libvirtd is as follow, which is similar to link: https://bugzilla.redhat.com/show_bug.cgi?id=906735, And it seems difficult to reproduce. Is there anyone have ever encounter this problem, is it a known bug, any information will be appriciated.

Subject: [Qemu-devel] qemu core dump when vnc client connect to VM, Is anyone has the similar problem, thanks!
Hi,
I’ve been tring to use QEMU-1.5.0 and Libvirt-1.1.0 to run a VM, but this problem comes up. The VM’s log by libvirtd is as follow, which is similar to link: https://bugzilla.redhat.com/show_bug.cgi?id=906735, And it seems difficult to reproduce. Is there anyone have ever encounter this problem, is it a known bug, any information will be appriciated.
Vm’log :

Yeah, I have experienced it before on some Fefora 18 installation with
the qemu and libvirt it packaged. Sadlly I didn't look deep into it at
that time. It appeared some time when I boot a linux guest changing its
size in startup sequence, or sometime vnc client resize. I guess it is
caused by vnc server side code, either in qemu or vnc library,
recommend try it with latest released qemu and report it later.
