[Bug 1822966] Re: apport-bug locks up when selecting "Cancel"

[Brian Murray]

I was unable to recreate this with apport version 2.20.10-0ubuntu25 from
disco on an Ubuntu mate desktop, using the apport-gtk frontend. When I
click "Other problem" I receive a dialog indicating that I need to
specify a package or PID and apport quits. Subsequently, I think this is
specific to the kubuntu frontend.

** Project changed: apport => apport (Ubuntu)

** Tags added: disco

** Tags added: kubuntu

Title:
  apport-bug locks up when selecting "Cancel"

Status in apport package in Ubuntu:
  New

Bug description:
  To reproduce:

  * Run "apport-bug" from the command line
  * Select "Other problem" from the "What kind of problem do you want to report?", then click OK.
  * The "What display problem do you observe?" dialogue pops up, I realise that doesn't match anything that I want to report and click Cancel.
  * Apport becomes completely unresponsive.

  Traceback after Ctrl-C suggests that there is a problem with a thread
  lock:

  Exception ignored in: <module 'threading' from '/usr/lib/python3.7/threading.py'>
  Traceback (most recent call last):
    File "/usr/lib/python3.7/threading.py", line 1281, in _shutdown
      t.join()
    File "/usr/lib/python3.7/threading.py", line 1032, in join
      self._wait_for_tstate_lock()
    File "/usr/lib/python3.7/threading.py", line 1048, in _wait_for_tstate_lock
      elif lock.acquire(block, timeout):
  KeyboardInterrupt

  This is on Kubuntu 19.04, apport 2.20.10-0ubuntu23
