(In reply to Holger Rumland from comment #0) > … only happens with the Theme engine QTCurve. … Smart observation. Thanks. If you choose a different theme engine – one with which Falkon does not crash – then revert to QTCurve, is the bug still reproducible? ---- Compare with https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=243362#c3 (closed, inspired by your observation) and bug 408701, although crashing bugs such as 408701 are associated with application startup (or session restoration).
Thank you for reporting this crash in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the crash with a recent software version? If you can reproduce the issue, please change the status to "CONFIRMED" when replying. Thank you!
Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed.
