Hello and sorry for the delay in responding to your bug report. Can you reproduce this crash consistently?
Comment 2 Martin Seidel 2020-05-01 09:23:22 UTC 
No it didn't happen again. I tried to open a folder while dolphin was counting the objects of each folder when it crashed

Comment 4 Julian Steinmann 2020-05-01 09:31:58 UTC 
Okay, thank you for the quick response :) Given that the backtrace looks very similar as in bug 417091, I'll close this report as a duplicate for now. Sadly, none of these reports can be reproduced consistently... Anyways, thank you for your report.
