This bug was fixed in the package gwibber - 3.3.92-0ubuntu1

---------------
gwibber (3.3.92-0ubuntu1) precise; urgency=low

  * New upstream release
    - determine if we are DST or not, and set isdst in the time struct. This
      fixes the time delta being off by an hour for DST.
    - Make sure we don't keep references to Dee.ModelIter that has been
      removed (LP: #937607)
    - Use the SHA1 hash of the avatar URL instead of simply stripping the
      slashes, to avoid the resulting filename being too long to be created
      on ecryptfs volumes. (James Tait) (LP: #845374)
    - improved error handling to UrlLib2Downloader (David Klasinc) (LP: #946049)
    - facebook: try to handle data from facebook of type=question to
      prevent empty posts in the feed
    - since gtk+ 3.3.18 scroll events are getting blocked in the Gtk.Label
      for message, so we need to add the event mask for it.
