NEW in 3.4.1 (04/25/2012)
============
* Use matching icons for unity lens categories
* catch GLib.GError instead of GLib.Error (LP: #940182)
* fallback to displaying full sender's name if the nickname is empty,
even if show-fullname is false (LP: #985801)
* foursquare: Don't crash on unicode characters in a users fullname, thanks
to Raza Sayed (LP: #975437)
* Defer calling unset on the seen HashMap until after we are done iterating
it, it will resize making the iterator invalid. (LP: #959068)
This is fixed in the 0.7 series of libgee
* Specify /usr/bin/python in gwibber-accounts instead of relying on
env (LP: #988385)
