It is quite hard to work on a bug which is not easily reproducible, and it looks like the error is probably elsewhere. For now, I'm closing the report; should you have more information or a way to reproduce the bug, please reopen it. Thanks.
Steps to reproduce are in the backtrace :P 1. run "ark" 2. click "New" and type "test.tar" in "Save As" dialog 3. click "Add File" 4. close Ark Main window behind the "Add Files" dialog => crash The "Add Files" dialog should be modal.
OK, reopening it then.
SVN commit 1231646 by rkcosta: Do not pass widget(), which is a QSplitter, as a parent to KFileDialog. Oh, we all love nested event loops. A QSplitter is passed as a parent to KFileDialog, which creates a KFileWidget. KFileWidget runs a nested event loop to stat the specified directory, which leads to posted events being processed, including QSplitter::childEvent(). childEvent() calls KFileDialog::show(), which shows the KFileDialog in a non-modal state. When KFileDialog::exec() is called, the dialog is already shown and is non-modal. BUG: 264819 FIXED-IN: 4.6.4 M +14 -1 part.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1231646
