It appears that check_for_crashes is not detecting the crash for some reason. Can you confirm that there was a crash dump in the minidumps folder within the profile on the emulator? Are you still able to reproduce this crash at all?

I don't know how to check there was a crash dump on emulator. However, it's still reproducible on try by reverting my changes to fix the crash

If there's a crash I believe we should have a 'minidumps' folder in the profile containing a .dmp crash dump file.
