This bug is due to the setup of the progress dialog being performed as part of the class initialisation. The dialog then receives no setValue signals for its default timeout (4 seconds) so it thinks the process is slow and shows the dialog.
My patch moves the setup of the progress dialog to the install method so doesn't get called until the user clicks the "Make Startup Disk..." button.
