[Bug 1204290] Re: panel crashed with SIGSEGV in indicator_object_get_entries()

[Tim]

my guess is this is crashing trying to load the session indicator which
we don't ship on the image.

(panel:2434): libindicator-WARNING **: File
'/usr/lib/indicators3/7/libsession.so' does not exist.

(panel:2434): GLib-GObject-WARNING **: invalid (NULL) pointer instance

(panel:2434): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion
'G_TYPE_CHECK_INSTANCE (instance)' failed

(panel:2434): libindicator-CRITICAL **: get_all_entries: assertion
