So the crash itself is due to GtkMenuItems created in entry_added() in indicator-applet hanging around after their IndicatorObjectEntry objects have gone. When they are activated, they start making function calls with the obsolete entry object and end up causing a crash.

This is borne out by the duplicates, which mention menu items sticking around from other applications. I haven't figured out why that happens yet, but am looking.

[Michael Terry (mterry)]

I'm having difficulty reproducing to find out how this situation occurs. Does anyone affected by this have suggestions for reproduction? Obviously I have to be not in unity, using the gnome-panel appmenu applet, but I've lived in it a little while, and nothing has come up.

The few duplicates don't not very useful descriptions...

[Sebastien Bacher (seb128)]

the bug was listed in this upload:

libdbusmenu (0.3.100-0ubuntu4) natty; urgency=low

  * libdbusmenu-gtk/parser.c
    - Ensure we set the CACHED_MENUITEM data on GtkWidget's, this fixes a few
      bugs (LP: #723463) (LP: #729128) (LP: #729194)

but not sure it does fix the crash as well or not

Marking as incomplete, as it was mentioned but we need confirmation that it's fixed. Thanks!

[Jungle Boy (mowgli80)]

I still have this problem with latest packages ... can confirm has not been fixed

[Ted Gould (ted)]

I'm going to go ahead and mark this as invalid so that if someone gets it again we can get a new stack trace. This one is too old to be of more use. Thanks everyone, hope we can get another trace.
