[SEG] Crash when working a lot with labels on label delete
Open, Unbreak Now!Public

Description

Not really reproducable but sometimes the application crashes when working with labels.
It seems like some kind of "race condition" and it seems correlated with deleting labels or groups.

After monkey testing in RelWDebugInfo, I think I found a lead. It can happen due to different processing of the Qt event queue that GetLabel is queried in a widget on a label that does not exist anymore. But it is not checked if GetLabel returns nullptr. Which in this case can happen. I hope this will fix the problem..,
