On a side note, does this issue occur with Oneiric (GTK 3.x) and above
as well?

Title:
  Call GTK functions without gdk lock

Status in Application menu module for GTK+:
  New
Status in “gtk+3.0” package in Ubuntu:
  New

Bug description:
  There ar ecalls to GTK functions without a gdk lock, which cause
  "random" crashes on mullti-threaded applications.

  The one that we hit is the call to 
    dsubmenu_gtk_parse_menu_structure 
    find_menu_bar
    ...
    rebuild_window_items
    do_rebuild
    <glib stuff>

  It is because is called vi g_timeout_add inside rebuild, which doesn't deal with gdk lock.
  It should call gdk_threads_add_timeout instead. 

  We found the bug running on Linux Mint.

  As a work around we setenv UBUNTU_MENUPROXY to nothing. 
  Other iseas?
