Bug 650223 - evolution-backup does not terminate without --gui
Use g_io_scheduler_push_job() instead of g_thread_create(). When the operation is finished, call gtk_main_quit() from the main thread using g_io_scheduler_job_send_to_mainloop(). Also, check for cancellation with a GCancellable instead of a boolean. Note: We really should be using GLib's process spawning API instead of system(), but that's a job for another day.
