SVN commit 996715 by modax: executeDelayedItemsLayout() on the nicknameListView after deleting the nick. This should ensure QTreeWidget internals do not keep deleted QTreeWidgetItem pointers around. This commit should solve the bug #200123. If you ever experience it again and/or the backtrace somewhat matches, please reopen the bug.
