My original report was on Windows.  The current report is on Debian
Squeeze against CEDET bzr repo.  So, consider this a bug report against
the "future"-CEDET.

When I do "C-c , j" on some symbol, that I know is defined in current
.el file, I get
,----
|     Jump to symbol: org-e-odt-lib-dir [No Match] [5 times]
`----

When I partially type up the symbol and do TAB for completion, I get
,----
|     semantic-analyze-current-context: Cannot analyze buffers not supported
|     by Semantic
`----

If semantic does not support EmacsLisp files [1],
1. It should report an error or warning when the buffer tries to enter
   semantic-mode.

2. Disable menu items (starting with Developement->etc) that doesn't
   apply to current buffer.

Footnotes: 
[1] Or for that matter a given language.

I have the following in my .emacs, as suggested by cedet help.
