Package: pyhoca-gui
Version: 0.5.0.3

Fedora rawhide is in the process of moving to wxPython 3.0 with gtk3 support.
 This appears to be breaking pyhoca-gui:

I believe this is because we are mixing a gtk2 based notify-python module with
the gtk3 wxPython module.  This seems like further impetus to move to a modern
python libnotify interface, either notify2 or gobject introspection Notify.

Code difference for gi appears to be:

Although with that change, unless I comment out the set_urgency() call, I
don't see the message "SSH key authentication has been successful." pop-up
above the pyhoca-gui icon.  But perhaps the new behavior is proper.
