Whole DrKonqi log with the problem
SUMMARY
Encountered a rather bad situation, where a crash reporter project gets an
exception itself, failing to report the actual crash it was supposed to handle.
STEPS TO REPRODUCE
1. Use Fedora Kinoite -> Universal Blue -> Aurora (getaurora.dev) derivative
atomic distro, rather regular KDE installation
2. Have DrKonqi configured to auto-send reports and grab symbols (both
checkboxes checked after first random app crash, in drkonqirc
DownloadSymbols=true and Sentry=true)
3. Have a random app crash
4. Have a DrKonqi notification displayed that a crash will be auto-send, and
you can either add a comment, restart the app or do nothing
5. Now everything should be okay, but you can also click Add a Comment which I
do
OBSERVED RESULT
If you open the DrKonqi window in step #5, it will report with a message at the
top that it's failed reporting the error, giving you an option to view log or
retry. The progress bar keeps moving. You have the option to enter crash
comment, but doing so and confirming **WILL NOT HAVE IT SENT ANYWHERE**
critically from UX-standpoint (which you could consider a separate UX bug on
its own, it sucks to pour some heart into descriptive bug report, but that
comment gets discarded, yikes). Besides said window also crashed on one attempt
as I finished writing the bug comment, which is also not nice.
Anyway, the real problem is the log has a bunch of lines like:
warning: Can't open file
/65/2cadaf974cb4dae6fd6815eb3913aaad7ae7dccf6bd922db9df17a10d4222a.file during
file-backed mapping note processing
Then DrKonqi ends up with `add symbol table from file "None"` trying to grab a
symbol from non-existent file, this throws a Python error (in
/usr/share/drkonqi/gdb/python/gdb_preamble/preamble.py, see whole log
attachment), which in turn shows `gdb.error: None: No such file or directory.`
and the whole script reports exit code 1 at the end. This causes Sentry crash
not to be sent. Neither of the Sentry envelopes dirs exist in ~/.cache/drkonqi
at all!
Note that if I view the actual crash dump's info in DrKonqi's browser, I do
generally see the crash info and symbols just fine. These suspicious files are
just at the bottom in what seems to be the way the actual executables were
launched in the stack:

EXPECTED RESULT
The crash report should go through, even if not all symbols could be loaded.
