While attempting to do-release-upgrade from 20.04 to 22.04, the upgrader crashed, and then the problem report script also crashed, leaving behind a corrupted crash report in /var/crash. This bug is about the problem report crash. I will report the upgrader crash separately.
Here are the last few lines of output:

[Impact]
Crashes in ubuntu-release-upgrader cannot be properly reported with apport.
[Test plan]
Seeing this issue requires causing another exception to be raised first. I do this like so:
* Start an upgrade, but say no when prompted to start the upgrade, after the tarball has been downloaded.
* Navigate to the tempdir where the tarball was unpacked, e.g. /tmp/ubuntu-release-upgrader-04y_8xfj
* Edit DistUpgradeViewText.py, and add a divide-by-zero in `confirmChanges`
* Observe that instead of an apport crash report being generated, there is an exception trying to do so:
Error in sys.excepthook:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 1: invalid start byte
[Where problems could occur]
The patch makes it so that u-r-u passes filenames, instead of open files, to apport to generate the report. Regressions would be seen in the generation of reports, or the format of the resulting report.
