Comment 2 Martin Klapetek 2015-11-23 20:01:42 UTC

Thanks for the reports

Can you reliably reproduce that crash? If yes, can you please install debug symbols for libtaskmanager and post updated backtrace?

Thanks

Comment 3 Lukas Jirkovsky 2015-11-26 20:20:50 UTC

Not really, it happened to me only once so far. But I will update the report if it happens again.

Comment 4 Martin Klapetek 2015-11-26 22:28:42 UTC

Alright, if it does, please reopen this report with the updated backtrace (make sure you have the debug packages installed for libtaskmanager).

Thanks.
