Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate a useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system

I discovered a bug in apport and with that fixed was able to get a better Stacktrace.
