Status changed to 'Confirmed' because the bug affects multiple users.

Seeing this in vivid now with daily image.

Cancelling the ubuntu-bug with CTRL+C returns the following output, not sure if it's useful:

Traceback (most recent call last):
  File "/usr/lib/python3.4/threading.py", line 1294, in _shutdown
    t.join()
  File "/usr/lib/python3.4/threading.py", line 1060, in join
    self._wait_for_tstate_lock()
  File "/usr/lib/python3.4/threading.py", line 1076, in _wait_for_tstate_lock
    elif lock.acquire(block, timeout):
KeyboardInterrupt

It took some seconds then closed. I don't have this bug.

[Bruce Pieterse (octoquad)]

Sherif, yes I noticed this behaviour yesterday, seems to be possibly fixed then.

[Bruce Pieterse (octoquad)]

I don't have this problem any more and apport seems to work correctly when doing this. I suppose this can be closed now.

When reproducing, everything works correctly. The status will be set to 'fix released' as it is no longer a problem. Thank you for reporting it!
