Your dialog has the plugin as parent? Change that to 0, so that
the dialog can't be deleted by any other means than itself being closed
(use e.g. WDestructiveClose).

kapp->ref() when showing the dialog, kapp->deref() when closing it.
This will ensure that the process doesn't exit until the dialog is closed.
