I was trying to investigate a failed retrace on armhf and received the following when running apport-retrace with -g.

When running apport-retrace with -o, a new crash file is created with a broken Stacktrace. This makes sense given that the core file is corrupt. I think apport-retrace should do something different here, maybe write a RetraceFailure key to the report, not write the report at all, or just exit with an error regarding the core file size difference.
