This bug was fixed in the package software-properties - 0.96.24.17

software-properties (0.96.24.17) artful; urgency=medium
* tests/test_dbus.py: Don't call GTK from multiple processes. We started
seeing software-properties tests failing with fatal X errors after GTK
I think it was the software-properties testsuite initialising Gtk,
forking and then calling Gtk from both the parent and child. I rewrote
the testsuite slightly to avoid that.
** Also affects: software-properties (Ubuntu)
Importance: Undecided
Status: New
** Changed in: gtk+3.0 (Ubuntu
