[Fix a crash that can happen if you have opened multiple views of
the summary and try to go off-line. This is not the correct fix, as the code should really be changed to only use one set of connections for all the views, instead of binding the connections to the view.] * e-summary-factory.c (e_summary_factory_new_control): Call `e_summary_offline_handler_add_summary()' instead of e_summary_offline_handler_set_summary()'. * e-summary-offline-handler.c: Replace member `summary' with `summaries' in the ESummaryOfflineHandlerPriv. This way, instead of assuming that there is only one summary, we keep a list of the summaries. (impl_destroy): Free ->summaries. (e_summary_offline_handler_set_summary): Removed. (e_summary_offline_handler_add_summary): New. Add the summary to ->summaries. Also, connect to the ::destroy handler so we can bookkeep them correctly. (create_connection_list): Made private from e_summary_offline_handler_create_connection_list(). Get a GSList instead of just one summary, and sum up all the connections from it. (impl_prepareForOffline): Use it. (impl__get_isOffline): Return %FALSE if any of the summaries are online, %TRUE otherwise. (impl_goOffline): Call ::set_online on all the summaries. Pass CORBA_OBJECT_NIL for the progress_listener as it doesn't really get used anyways. (impl_goOnline): Likewise. Pass CORBA_OBJECT_NIL, not NULL, for the progress CORBA_Object pointer. svn path=/trunk/; revision=15547
