Could you tell us what you were doing when this crash occurred (if you remember)? That would make it possible to try to reproduce the bug. Thank you!
Thanks for triaging, Russel, but the steps are given. What is missing are debugging symbols for this backtrace to be useful. To the reporter: please install debugging symbols and provide a new backtrace if this crash is reproducible.

Thanks, It did not happen again yet, when it does I will do as you said.
