I started dragging a thread and one standalone unthreaded message; I was going to move them to another mailbox. Another message arrived in the meanwhile. That message was going to become a part of that existing thread that I was dragging. Here's a backtrace. There was no assert crash, just a segfault: (gdb) bt #0 0x00007feb49c2f30d in QSortFilterProxyModel::parent (this=0x27a3790, child=...) at
