Thank you for the crash report.

As it has been a while since this was reported, can you please test and confirm
if this issue is still occurring or if this bug report can be marked as
resolved.

I have set the bug status to "needsinfo" pending your response, please change
back to "reported" or "resolved/worksforme" when you respond, thank you.

Heya Yuri,

unfortunately it's not possible to reproduce the crash using your file (it is
not standalone, needs other includes, thus cannot be parsed properly here).

It would be best if you could supply a backtrace of your crash, please check
out the following link to see how to create a crash report on Linux:
