It got stuck this time too in QListView::itemAbove, where it was stuck in: while( c && c->siblingItem != this ) c = c->siblingItem; because c was the same as c->siblingItem. So I added asserts in qlistview.cpp everywhere where siblingItem was assigned to something, to check if there were any assignments of the kind item->siblingItem = item And the assert was triggered when trying to delete the same message again with this backtrace: Using host libthread_db library "/lib/tls/libthread_db.so.1". `system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.

__libc_start_main () from /lib/tls/libc.so.6 #53 0x0805bfe1 in _start () Line 1177 in qlistview.cpp is: newChild->siblingItem = childItem; and the assert was triggered because newChild was equal to childItem. And around line 1088 in kmheaders.cpp is: 1084 if ( parent && parent->item() != item && parent->item() != removedItem ) { 1085 parent->item()->insertItem(lvi); 1086 parent->addSortedChild( sci ); 1087 } else { 1088 insertItem(lvi); 1089 mRoot->addSortedChild( sci ); 1090 } So as far as I understand it, it tries to add an item to the root of the listview when it's already a child of the listview. Also, looking at the thread I was trying to delete, the message I tried to delete was the parent of two messages when using "Thread messages also by Subject", but when unchecking subject-threading it was only the parent of one of them. _______________________________________________ KMail developers mailing list KMail-devel@kde.org https://mail.kde.org/mailman/listinfo/kmail-devel
