[Bug 1833795] [NEW] unable to report an 18.04 crash from a 19.04 system

[Brian Murray]

Public bug reported:

I had a distribution upgrade crash when I was trying to upgrade from
18.04 to 19.10 and a .crash was generated. I didn't want to report it
from the system which crashed so I ran apport (to do the data
collection) and saved the information in the report. I then copied it
over to another system which is running Ubuntu 19.04 and I could not
report the crash as I received the following crash.

 $ ubuntu-bug tmp/_usr_bin_do-release-upgrade.0.crash      
Traceback (most recent call last):
  File "/usr/share/apport/apport-gtk", line 597, in <module>
    app.run_argv()
  File "/usr/lib/python3/dist-packages/apport/ui.py", line 704, in run_argv
    self.run_crash(self.options.crash_file, False)
  File "/usr/lib/python3/dist-packages/apport/ui.py", line 291, in run_crash
    if not self.report and not self.load_report(report_file):
  File "/usr/lib/python3/dist-packages/apport/ui.py", line 1375, in load_report
    self.report.load(f, binary='compressed')
  File "/usr/lib/python3/dist-packages/problem_report.py", line 144, in load
    block = base64.b64decode(line)
  File "/usr/lib/python3.7/base64.py", line 87, in b64decode
    return binascii.a2b_base64(s)
binascii.Error: Incorrect padding

I've attached the problematic crash file, although I don't really think
it is the crash file that is the issue.
