Comment 1 Justin Zobel 2021-01-03 01:16:31 UTC

Thank you for the crash report. In order to diagnose this issue as quickly as possible can you please ensure you have all debug symbols installed.

Instructions on how to do this for several distributions is provided at: https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Install_debugging_packages

Once you have all the debug symbols installed (see lines where it has "in ?? () from" for hints on which packages are needed) please reproduce the crash and upload the new backtrace, thank you.

Comment 2 Dan Leinir Turthra Jensen 2021-01-14 10:49:51 UTC

As far as i can tell, this should be fixed as of https://invent.kde.org/graphics/peruse/commit/d21dc367a9dd29fda1bbe5857b7896b7bf523d5b, but testing would be appreciated :) I'm going to close it for now, at least, i can't provoke this crash any longer (getting another one very occasionally, but that's in the pdf generator, which... not sure what's going on there)
