Virt-manager itself opens, and allows you to run machines or perform maintenance with the control panel. Attempting to spawn a VM window (to actually view the console or details) however doesn't work. virt-manager --debug spits out the following error:

Installing gtksourceview4 from the extra repository solves this problem (everything works fine). The prior virt-manager version (2.1.0-2) does not need gtksourceview4 installed to function, so this appears to be a new required dependency for virt-manager 2.2.0.

Additional info:
* package version(s)
* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:

As above: open virt-manager 2.2.0 and it loads, but will not load a console/details window of any VM. Installing gtksourceview4 resolves this issue, and it is not listed as a dependency or optional dependency for virt-manager 2.2.0.
This task depends upon

It seems this dependency was added because of the "libvirt XML viewing and editing UI for new and existing domain, pools, volumes, networks".
The last virt-manager release only supports gtksourceview4 but in git the code it seems that the next version could also run with gtksourceview3.

+1 here, I was surprised today by unusable virt-manager. Took some time to understand, what's happening.
