Comment 9 for bug 805906

Analysis while checking #837870:

1. Run KDE Partition Manager from the Live CD.
2. Modify something so an operation is added to the list of pending operations.
3. Quit the application without applying operations. It will ask if you really want to quit, spawning a knotify process to do that.
4. Agree to quit without applying operations.
5. Shutdown the system. It will ask for confirmation, then just sit there, apparently fully usable.
6. Find root's knotify process in a shell. Kill it.
7. Shutdown proceeds.

Note the behaviour has probably nothing at all to do with KDE Partition Manager. It's just one application that spawns a knotify process.

This issue should probably be taken to bugs.kde.org if it's not there already.
