tmm-menubar not showing any menu items?

[Lachlan Deck]

Hi there,

(for emacs 24~HEAD from a few weeks ago)

if I start up emacs without any customisations (i.e., emacs -Q), tmm-menubar 
works as expected, showing the buffer of options to choose from via a single 
letter.

However, with my customisations in place many times I find the tmm-menubar 
fails to show anything but the following:
----------------------------------------------------------------
Press PageUp key to reach this buffer from the minibuffer.
Alternatively, you can use Up/Down keys (or your History keys) to change
the item in the minibuffer, and press RET when you are done, or press the
marked letters to pick up your choice.  Type C-g or ESC ESC ESC to cancel.
In this buffer, type RET to select the completion near point.

There are no possible completions of what you have typed.
----------------------------------------------------------------

i.e., no options at all. How would I track down why this is failing?
