Bug 397028

If I click on the main window exit button (this little "x" or hitting ALT+F4) after some videos are played, the main window disappears together with its big taskbar icon but the small kaffeine icon in the notification area is still visible. Before using kaffeine again I have to kill the dead kaffeine task. No problem when the program is terminated with File->Quit or if I haven't played any videos (video file or tv).

Example output of gdb when kaffeine is in "ghost" mode (the numbers are changing):
