Yesterday I did a large amount of archiving email from the year 2020 (I keep about 3 GiB of emsil archives, in total). After running the rsync script, I started Dolphin to look at the backed up copy of the email archive, which had been recetnly reorganized. It worked fine at first -- I drilled all the way down (tree view) through 4 levels of directories to an actual list of files. The crash occuirred when I clicked the down arrow to collapse the file list. No other application programs were running except yakuake and the usual cadre of kde framework stuff. I started dolphin again, repeated my previous sequence of actions, and boom! It died the same way. The only difference I can see is that the "KDE Crash Handler" was running the second time it crashed. I should mention that i re-compiled a lot of kde-framework packages just two days ago, on 11 January. Big package upgrade at Gentoo (I try to run emerge --sync once a day). 60 packages were affected. Upgraded from 5.74 to 5.77. It took 7.5 hours to compile those 60 packages (I maintain a complete set of "portage" log files for all 1288 packages installed on my system). The day before (10 January) I installed qt5.15.2 and a few additional packages (firefox, libre-office) dependent on qt. 4.5 hours for that one, My poor CPUs are getting tired. :-) The crash can be reproduced every time. -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault [KCrash Handler] #4 0x00007fe460073aec in KFileItem::~KFileItem() () from /usr/lib64/libKF5KIOCore.so.5 #5 0x00007fe4606d3c10 in KFileItemModel::removeItems(KItemRangeList const&, KFileItemModel::RemoveItemsBehavior) () from /usr/lib64/libdolphinprivate.so.5 #6 0x00007fe4606e0a65 in KFileItemModel::setExpanded(int, bool) () from /usr/lib64/libdolphinprivate.so.5 #7 0x00007fe4606f4e00 in KItemListController::mouseReleaseEvent(QGraphicsSceneMouseEvent*, QTransform const&) () from /usr/lib64/libdolphinprivate.so.5 #8 0x00007fe4606f6321 in KItemListController::processEvent(QEvent*, QTransform const&) () from /usr/lib64/libdolphinprivate.so.5 #9 0x00007fe4607053f6 in KItemListView::event(QEvent*) () from /usr/lib64/libdolphinprivate.so.5 #10 0x00007fe45f21fd8f in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /usr/lib64/libQt5Widgets.so.5 #11 0x00007fe45f228a40 in QApplication::notify(QObject*, QEvent*) () from /usr/lib64/libQt5Widgets.so.5 #12 0x00007fe45e74b337 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () from /usr/lib64/libQt5Core.so.5 #13 0x00007fe45f547e83 in ??
