Bug#861186: Xorg crash / Assertion uxa_pixmap_is_offscreen(src_pixmap) failed
Package: xserver-xorg-core
Version: 2:1.16.4-1
Severity: important
I'm running a virtual machine in KVM/libvirt and accessing it with SPICE
/ virt-viewer. The VM and the virt-viewer systems both run jessie.
I logged in, opened a couple of terminal windows and then clicked to
open Firefox and the desktop crashed and went back to the gdm login screen.
Looking at journalctl I found the following:
Apr 25 15:41:05 iceweasel.desktop[3219]: Gtk-Message: Failed to load
module "canberra-gtk-module"

and then there are a whole bunch of other errors before gdm / Xorg
restarts itself.
A similar crash had happened once before.
