Same here - twitter:receive fails with the exact same TypeError: 'NoneType' object is unsubscriptable.

Same is happening for me, and I'm not using the latest trunk, but the latest official version from the Ubuntu repositories. I'm on Lucid 64-bit and the version of Gwibber is 2.30.1-0ubuntu1. Since this morning, Twitter message are no longer being shown by Gwibber, and the exact same message as listed above is displayed by gwibber-service.

I've read the Twitter class code and changed some things trying to the discover the cause of the bug. I think there's something new with twitter (i don't know how is the tech spec about the json format returned by twitter), but for some messages, theres a null value in the returned json.

I've corrected this bug adding this little hack to twitter.py, at line 78:

def _message(self, data): # this line already exists
    if type(data) == type(None) :
       return []
