Popup notification window, font color could be fixed too.
Popup notification window colors are fixed (which is not a bad thing btw), but the font color depends on the current gtk theme, so it can happen that this combination may look strange sometimes:

It'd be good to set {event_type,event_description}_label foreground color to black.
A patch:
