[Pkg-libvirt-maintainers] Bug#941389: virt-manager: Missing dependency from gir1.2-gtksource-4

[manul]

Package: virt-manager
Version: 1:2.2.1-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

After upgrading virt-manager to the latest version, once started it is unable to open virtual machine details/console pop windows (as well as some other pop windows like connection settings etc).
Installing gir1.2-gtksource-4 fixes the issue but, it is not in the current dependencies of virt-manager (which I believe it must be).

Thank you.
