[Robbie Harwood]

Package: virt-viewer
Version: 1.0-1
Severity: important

Dear Maintainer,

When attempting to connect to VMs over SPICE, virt-viewer will consistently
segfault as so:

$ gdb -q virt-viewer
Reading symbols from virt-viewer...(no debugging symbols found)...done.
(gdb) set args --connect qemu:///system 1
(gdb) r
Starting program: /usr/bin/virt-viewer --connect qemu:///system 1
