A few thoughts:

1. The corrupt line #2 in Stacktrace is likely to be  indicator-
appmenu/src/huddbusmenucollector.c's
hud_dbusmenu_collector_property_changed(). dbusmenuitem's "property-
changed" signal is the only one whose signature matches the void-string-
variant one in Stacktrace's 3rd line.

2. So it looks like this crash is coming in huddbusmenucollector.c when
the collector->items hashtable pointer is corrupt (to the very
suspicious value 0xaaaaaaaa). However I don't see in the source code how
that's happening.

3. Also, indicator-appmenu's gone through very heavy development over
the last couple of months. In fact there have been 5 releases (the
latest being 0.3.97) since the one involved in this crash (0.3.92) and
the code involved in this crash has gone through heavy rewrites in that
interval.

So I think what we need here is to know whether the crash is
reproducible in a newer version of Ubuntu. It would help us greatly if
you could test with it so we can work on getting it fixed in the next
release of Ubuntu. You can find out more about the development release
at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your
help.
