This is a somewhat fundamental Qt/KAccel problem. The Ctrl-W keypress is handled *BEFORE* the modal dialog is into place that is supposed to prevent that. A similar problem can be seen when in e.g. kedit when you press Ctrl-O (Open File) twice in quick succession. The second Ctrl-O then gets processed as part of the event loop for the first file open dialog resulting in a second file open dialog.
Created attachment 4475 [details] Patch to suppress kaccel handling when a modal dialog is there. The problem is caused by KAccelEventHandler::x11Event( XEvent* pEvent ) in kaccel.cpp. Attached patch seems to fix it by eating key events for the old focus widget if a modal widget is showing in the meantime.
