If the intent was to have apport-unpack deal with any invalid crash file, then
it's not complete. This still happens now:
ubuntu@k-apport:~$ apport-unpack /bin/ls unpack
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/problem_report.py", line 174, in load
(key, value) = line.split(b":", 1)
ValueError: not enough values to unpack (expected 2, got 1)
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/usr/bin/apport-unpack", line 66, in <module>
pr = load_report(args.report)
File "/usr/bin/apport-unpack", line 47, in load_report
pr.load(f, binary=False)
File "/usr/lib/python3/dist-packages/problem_report.py", line 177, in load
f"Malformed problem report: Line {line.decode()!r}"
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb0 in position 24:
invalid start byte
Is this something you would still like to address?

Title:
apport-unpack cannot load gitkraken crash report - 'ascii' codec can't
decode byte 0xfc in position 56

Bug description:
Impact
======
apport-unpack and whoopsie-upload-all can crash when fed with a
malformed problem report. They should print a proper error message
instead of crashing. This bug does not happen that often, but the fix
for this bug is the foundation for the fix for bug #1995100.
Test Plan
=========
1. Create malformed report:
```
printf 'AB\xfc:CD\n' > malformed.crash
```
2. Try to unpack it:
```
apport-unpack malformed.crash unpack
```
It should print an error message instead of a stack trace.
Where problems could occur
==========================
The patch touches the problem report handling and therefore can affect
apport-unpack, apport-bug, whoopsie-upload-all. The change is covered
with tests and apport has a test suite running during build and as
autopkgtest.
Original report
===============
The latest GitKraken client (8.10.2 x64) is crashed every minute in
cycle when you doing a rebase. When I try to inspect crash log to find
the reason, the apport-unpack is not be able to process it:
/var/lib/apport/coredump$ sudo apport-unpack
core._snap_gitkraken_199_usr_share_gitkraken_gitkraken.1000.5de91c04-23ab-45c8-933c-0466d56e9fad.135785.50225891

Unfortunately, crash file is too big (~9GB) and does not compress
further
