Comment 5 for bug 297324

My versions are:
python-simplejson (1.9.1-1ubuntu1~ppa0)
python-webkitgtk (1.0.1-0ubuntu2)
gwibber (0.7~bzr120~hardy~ppa1)

I'm in a Intrepid box that was updated with dist-upgrade from a hardy one. I'm not able to use gwibber now with this last gwibber update, it hangs, but only when I set it up to also receive messages, not just send them. I have one identi.ca and one twitter account set up.

It freezes and spits the following in the console:

Exception in thread Thread-1:
Traceback (most recent call last):

I've also tried the remove --purge approach, with no results.
