Thank you for your report!

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might be caused by some outdated packages which were installed on your system

Thank you for reporting this bug.

Given the problem in processing the stack trace, and given that we have bug 801161 which is also about a crash in the same function (but we have more info on that bug), I'll mark this bug as duplicate.
