Bug Description

Binary package hint: virt-manager

Ubuntu release: 10.10
virt-manager version: 0.8.4-3ubuntu6

I have attempted installation of XP Home 5 times and it has crashed at a different point every time. It seems to occur as I'm moving the mouse pointer in to or out of the window. The crash has only happened during the first part of the install, when the screen is in "dos mode".
Also, the virtual machine seems to be fine; it stays running in the background. It's only virt-manager that crashes.

More information:
I have also experienced this cash while running the XP guest after installation. Most frequently it happens when moving the mouse into or out of the console window, but I've also had it happen when clicking various menu items and once when it was just sitting there, with no input at all.

I'm changing the status back to new, since I'm the OP and the commenter, and I don't think I'm allowed to confirm my own bug.
More information:
I've now experienced this bug with Windows 7 32 bit and Windows 98. The Windows 98 VM was using QEMU - it won't boot with KVM. At this point, I'm going to guess that the version of Windows doesn't matter.
On all Windows versions, I've seen it more frequently when the VM is configured to use the 'vga' video type than I have with the 'cirrus' type.

Have you seen this issue with gtk-vnc 0.4.1-3ubuntu1?

I installed all the latest updates today, among them a new version of python, and I haven't been able to reproduce since then.
