gwibber-accounts crashed with TypeError in __init__(): Gtk.Window.set_icon_from_file() argument 1 must be string, not None

Confirmed and 100% reproducible here

Same here with Gwibber 3.1.4 on Oneiric, too, each time I want to open Accounts manager I get this error message :

Traceback (most recent call last):
  File "/usr/bin/gwibber-accounts", line 112, in <module>
    accounts.GwibberAccountManager(selected_account=selected_account, condition=condition, message=message)
  File "/usr/lib/python2.7/dist-packages/gwibber/accounts.py", line 58, in __init__
TypeError: Gtk.Window.set_icon_from_file() argument 1 must be string, not None

Here is the crash file for Gwibber account bug.

Xavier, please do not attach .crash files into reports, instead please use apport or double click into this file and apport will recollect all the necessary information.

Curious...what's the reasoning behind marking this bug as medium. Basically gwibber is broken, because you can't add any accounts, so I would think this to be a High/Critical issue. Is this only affecting people with existing accounts, i.e. an upgrade? Is there a workaround to avoid this? Does this only happen for a specific Oneiric configuration? Not trying to be an @$$, just wanting to understand the reason for the "Medium" importance classification.

Based on the number of dupes, I guess I need to raise the priority. It isn't happening for everyone, but not sure what the specific history is for the users hitting it. It is only for upgrades, and not all upgrades.

The problem seems to be related to switching from pycentral to dh_python2, it isn't cleaning up the old .pyc files. The Work around is to remove /usr/lib/python2.*/dist-packages/gwibber

It looks like i need to clean those files in the package, but I would think pycentral should do that automatically, so want to ask around first.

This bug was fixed in the package gwibber - 3.1.4+r1093-0ubuntu2

gwibber (3.1.4+r1093-0ubuntu2) oneiric; urgency=low

Just installed 3.1.4+r1093-0ubuntu2 but I still have the .pyc files in /usr/lib/python2.*/dist-packages/gwibber and getting the same crash. Manually removing the files made everything work.

What version did you upgrade from?

I also still have the same problem with Gwibber 3.1.4+r1093 normally upgraded from Ubuntu Oneiric packages (no ppa).
