[cedet-semantic] Debugging with semantic-1.4.4

[<WZ...@t-...>]

*,

when I follow the instructions for debugging (Chapter 8 Debugging) language
files using BNF with "bovinate-debug" I mostly have no success.

Here is the scenario: I have a simple c-file hello.c, the c.bnf
grammar-description as source and the corresponing lisp-table in semantic-c.el
all in my current working directory. semantic is installed properly (I hope)
with 

        (setq semantic-load-turn-everything-on t)
        (require 'semantic-load)
 
and semantic-load leaving untouched, i.e. the distributed version.

Now I open two files; one buffer contains hello.c, another buffer
semantic-c.el, I point to the table-structure in semantic-c.el and execute
 semantic-bovinate-debug-set-table. Then I set the pointer to the beginning of
hello.c and execute bovinate-debug: the buffer containing semantic-c.el
disappears and is replaced by *BOVINATE* which only contains one line with
"nil". But sometimes, after endless trials, I get the layout described in the
manual and the point now sits on the rule in the table corresponding to the
token found in the c-source file and I can get through the source hitting the
space-key ...

Whats wrong with my setup? 
What can I do to debug against the c.bnf file?

Thanks in advance
Wolfgang
