[Reportbug-maint] Bug#769055: reportbug: AttributeError: 'NoneType' object has no attribute 'startswith'

[Brian May]

Package: reportbug
Version: 6.6.0
Severity: important

Not only did it crash, but there doesn't seem to be any sign of the temp
file any more, so I had to retype the bug report :-(


Report will be sent to "Debian Bug Tracking System" <submit at bugs.debian.org>

  File "/usr/lib/python2.7/posixpath.py", line 261, in expanduser

AttributeError: 'NoneType' object has no attribute 'startswith'


Looking at the code:

elif outfile or not ((mta and os.path.exists(mta)) or smtphost):
    msgname = os.path.expanduser(outfile) or ('/var/tmp/%s.bug' % package)$


It would appear to be that outfile is None (not sure I understand why),
however the condition gets satisfied if a MTA is not installed or is
smtphost is defined.

It then crashes.

If this is an error condition, there needs to be a better error message,
and even better the temp file created by the editor should not get deleted.

Thanks
