Currently gnome-control-center could crash whenever a connection test is interrupted by the disposal of the Printers panel. Searching in the g-c-c shell for any query that could match the Printers panel would instantiate the CcPrintersPanel class. Since we perform a connection test to the printing server as soon as this object is created, a fast disposal of the panel (by choosing another search result) would cause the whole application to crash. https://bugzilla.gnome.org/show_bug.cgi?id=792753
