The probable cause of that is a race condition; and broken-ness here: libbonobo/activation-server/object-directory-corba.c (as_rescan) static gboolean as_rescan (gpointer data) { ObjectDirectory *od; static gboolean in_rescan = FALSE; static guint idle_id = 0; server_lock (); if (!(od = main_dir)) { /* shutting down */ server_unlock (); return FALSE; } /* We tend to get a lot of 'broken' callbacks at once */ if (in_rescan) { if (!idle_id) idle_id = g_idle_add (as_rescan, NULL); server_unlock (); return FALSE; } Looks like we need to un-set idle_id. Having said that: we are shipping a libbonobo such that b-a-s should quit when it sees the b-a-s session bus die [ there is a fairly ~evil patch to do this in libbonobo - without a dbus connection interestingly ;-) ] but - unfortunately, the session bus is never exiting. Initially I thought this was due to the huge leakage of gvfs pieces - Hans Peter: when is gvfs going to stop pooing in my process tree ? :-) Unfortunately, having killed them all it seems there is a further simple leak of dbus session busses this is really disturbing (from the console): $ ps auwx | grep julia julia 3472 0.0 0.0 2412 832 ?
