Confirmed since I'm also seeing this (in my case on firefox 3.6.8+build1+nobinonly-0ubuntu2 - and a lot of other programmes).
Note I do not have appmenu-gtk installed - it was installed but I apt-get removed it.

Ah - I think I might see what's happening here.
  1) Installing appmenu-gtk adds /etc/X11/Xsession.d/80appmenu
  2) This sets the environment variable UBUNTU_MENUPROXY to libappmenu.so
  3) If you remove appmenu-gtk the variable is still set - and you get these errors
  4) apt-get remove on appmenu-gtk leaves behind the /etc/X11/Xsession.d/80appmenu causing these errors to persist.

To clarify something; I added this as a bug against gtk+ because I think it's the mechanism that's broken not necessarily appmenu-gtk specifically - I think it's doing what the mechanism is expecting, but I really don't think that mechanism is right.

Also this produces a whole stream of errors - this mechanism gets triggered 10s-100s of time for each application start;
besides the fact it can't do anything for performance even when it's working correctly, it's producing tonnes of errors in this case.
It should be checking this at most once on any app startup.

I believe the 'undefined symbol: menu_proxy_module_load (firefox-bin:16169):'

is coming from the code in 043_ubuntu_menu_proxy.patch in ubuntu_menu_proxy_module_real_load
Nothing checks the return value of _gtk_find_module so the call to g_module_open (being passed null) returns the main program as a module - and that's where the symbols get looked up.

The 'Failed to load type module' is probably from 'ubuntu_menu_proxy_module_get' in the same file; the (null) is again coming from an unchecked return from _gtk_find_module.

thanks for your bug report. seems there is a similar bug already with a better title. marking duplicate

[dino99 (9d9)]

hi Omer,

this bug is older than bug#674047 (reported 6 month ago !!!)

 and if you look at: how to reproduce it : 674047 talk about unity, not this one

so bug#674047 is a duplicate of this one (i dont care if you change it for a better title if that can help to fix it !!!!)

Marking again as a duplicate of bug 674047, which is already fixed.
