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

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

[1] Or for that matter a given language.

I have the following in my .emacs, as suggested by cedet help.
|     ;; Load CEDET.
|     ;; See cedet/common/cedet.info for configuration details.
|     ;; IMPORTANT: For Emacs >= 23.2, you must place this *before* any
|     ;; CEDET component (including EIEIO) gets activated by another 
|     ;; package (Gnus, auth-source, ...).
|     (load-file "~/src/cedet/cedet-devel-load.el")
|     ;; Add further minor-modes to be enabled by semantic-mode.
|     ;; See doc-string of `semantic-default-submodes' for other things
|     ;; you can use here.
|     (add-to-list 'semantic-default-submodes 
'global-semantic-idle-summary-mode t)
|     (add-to-list 'semantic-default-submodes 
'global-semantic-idle-completions-mode t)
|     (add-to-list 'semantic-default-submodes 'global-cedet-m3-minor-mode t)
|     ;; Enable Semantic
|     (semantic-mode 1)
