apport appears to crash. Spinner never stops. KeyError: 'ProblemType'

[crf]

Apport doesn't seem to close properly. It seems to send the problem report to Launchpad, but doesn't tell the user that the problem has been reported. It just spins its spinner.
The following is printed on the command line.

This doesn't happen all the time. I just sent a report for a different issue using apport. And Apport worked properly this time.

[Launchpad Janitor (janitor)]

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

This release of Ubuntu is no longer receiving maintenance updates. If this is still an issue on a maintained version of Ubuntu please let us know.
