Seems to happen at least when filtered results are found under both various artists and under single artists. Reading docs ( https://doc.qt.io/qt-5/qmodelindex.html ), "If you need to keep a model index over time use a QPersistentModelIndex." is probably relevant here. I didn't do too deep analysis on the paths leading here, but the crash is caused when the static_cast at row 444 of CollectionTreeItemModelBase.cpp is erroneous (parent.internalPointer() seems to be a non-QObject). So something causes a data-changing change when both kinds of results are in the filtering. Seems to be fixed by having a QPersistentModelIndex instead.

Created attachment 154974 [details] New crash information added by DrKonqi amarok (2.9.71) using Qt 5.15.7 - when searching the collection (either by typing search terms or by selecting them from the advanced dialog), after submitting / shortly waiting, the application crashes before results become visible (i.e. before the collection tree seems to be refreshed) - crashes are always reproducible with the same (affected) search terms - some search terms yield results without a crash - using an external mariadb with a very large collection -- Backtrace (Reduced): #4 QListData::isEmpty() const (this=0x560ef5c59cb0) at /usr/include/qt5/QtCore/qlist.h:116 #5 QList<CollectionTreeItem*>::isEmpty() const (this=0x560ef5c59cb0) at /usr/include/qt5/QtCore/qlist.h:201 #6 CollectionTreeItem::row() const (this=this@entry=0x7f1b4fbf6cc0) at /var/tmp/portage/media-sound/amarok-9999/work/amarok-9999/src/browsers/CollectionTreeItem.cpp:227 #7 0x00007f1b512541c0 in CollectionTreeItemModelBase::itemIndex(CollectionTreeItem*) const (item=0x7f1b4fbf6cc0, this=0x560ef3e50a60) at /var/tmp/portage/media-sound/amarok-9999/work/amarok-9999/src/browsers/CollectionTreeItemModelBase.cpp:582 #8 CollectionTreeItemModelBase::itemIndex(CollectionTreeItem*) const (this=0x560ef3e50a60, item=0x7f1b4fbf6cc0) at /var/tmp/portage/media-sound/amarok-9999/work/amarok-9999/src/browsers/CollectionTreeItemModelBase.cpp:577
Somewhy the automatic closing of a bug by a commit didn't kick in here. Anyway, this should be now fixed in current git head (since 7th Feb 2023) with https://invent.kde.org/multimedia/amarok/-/commit/2b1f73b0f6f3c3e63097b0820da4f6d12e5c377c?merge_request_iid=50
