Comment 4 for bug 641121

The behaviour is not exactly the same since as #607405 i don't get a crash, gwibber continues to work, and apport does not run.
However i see the following in the terminal when running gwibber from command line:

Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/gwibber/client.py", line 428, in <lambda>
    about_dialog.connect("response", lambda *a: about_dialog.hide())
NameError: free variable 'about_dialog' referenced before assignment in enclosing scope
