My patch works by ensuring the apport can handle the number of arguments
being passed such that print_usage() is never called so we won't
Traceback trying to write to a non-existent file.

Bug description:
The Ubuntu Error Tracker has been receiving reports about a problem
regarding apport. This problem was most recently seen with package
version 2.20.11-0ubuntu27.10, the problem page at
https://errors.ubuntu.com/problem/290470c9cf5f278596966c386aac31e70a49988e
contains more details, including versions of packages affected,
stacktrace or traceback, and individual crash reports.
Traceback (most recent call last):
File "/usr/share/apport/apport", line 451, in <module>
options = parse_arguments()
File "/usr/share/apport/apport", line 396, in parse_arguments
parser.print_usage()
File "/usr/lib/python3.6/argparse.py", line 2370, in print_usage
self._print_message(self.format_usage(), file)
File "/usr/lib/python3.6/argparse.py", line 2381, in _print_message
file.write(message)
AttributeError: 'NoneType' object has no attribute 'write'
After working on https://bugs.launchpad.net/apport/+bug/1732962, the error
tracker started throwing the error above.
it appears that print_usage is called and throwing an error because in this
context (called with core_pattern) apport doesn't have an stdout or stderr.
after looking at traces it seems the kernel is adding 'deleted' to the name of
the process which cause argument parsing to fail.
The fix below from bdmurray seems to fix it.
