I've found the trigger. virt-manager crashes after taking a screenshot and focusing the window again.

Comment 15 Kamil Páral 2016-05-24 08:35:52 UTC
virt-manager does not crash with
and crashes with

The reproducer is simple:
1. boot a Fedora Workstation into graphics (using Spice+QXL)
2. take a screenshot using the virt-manager window menu
3. focus the VM with a cursor, it crashes

Comment 16 Kamil Páral 2016-05-24 08:39:57 UTC
gtk3-3.20.5-1.fc24.x86_64 has been unpushed from testing updates and gtk3-3.20.6-1.fc24.x86_64 has been proposed instead, which fixes the regression. Closing.
