Bug#762658: baobab: Fails to start properly: Invalid template parent type `Gtk.ApplicationWindow'

[Peter De Wachter]

Package: baobab
Version: 3.12.1-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

When I start baobab, it shows an empty window, without any widgets. The
application is completely non-functional. I've included the messages that are
logged on stderr below.

Perhaps this was caused by the recent upload of GTK 3.14?
