Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

This looks also a libindicator issue to me, on a stacktrace I mostly get this:

#0 0x0000000000406a2f in panel_indicator_entry_accessible_get_n_children (
    accessible=0x2a50840)
    at /home/u/Dev/unity-trunk/services/panel-indicator-entry-accessible.c:256
        __inst = 0x7f25e402e090
        __t = 32191904
        __r = 0
        piea = 0x2a50840
        n_children = 0
        __PRETTY_FUNCTION__ = "panel_indicator_entry_accessible_get_n_children"

With:
(gdb) print piea
$1 = (PanelIndicatorEntryAccessible *) 0x2a50840
(gdb) print piea->priv
$2 = (PanelIndicatorEntryAccessiblePrivate *) 0x2a50890
(gdb) print piea->priv->entry
$3 = (IndicatorObjectEntry *) 0x2a39020
(gdb) print piea->priv->entry->parent_object
$4 = (IndicatorObject *) 0x3

This last pointer looks very odd to me.

I was wondering about activity on this bug. The bug has many duplicates and a high heat number. The last activity seen here is for October of last year. Ubuntu 12.04 is scheduled to be serviced for a few more years. I have been suffering with this problem for a year. Is there any progress to report?
