LIBDBUSMENU-GTK-DEBUG: Could not handle image type 6

When trying to post to ping.fm, it never works.
It's working when I post to only one service (statusnet).

Running gwibber in the foreground, yields:

Running the following on Natty, freshly updated today:
gwibber 3.1.0~bzr990-0ubuntu1~daily1
(it has been broken for a while - at least ~3 weeks I believe)
