problem at compiling for html

[Roland Goretzki]

Hi at all,

about the last two years there was ALWAYS a warning at invoking
lilypond, but nevertheless I was always satisfied by the output, so that
I didn't mention it.
The warning was:

    /usr/bin/lilypond:666: SyntaxWarning: local name 'e' in
    'make_html_menu_file' shadows use of 'e' as global in nested scope
    'lambda'
      def make_html_menu_file (html_file, files_found):
    
Now that I tried to invoke lilypond as follows

     lilypond --html satz-4.ly

the problem results in an error:

    Traceback (most recent call last):
      File "/usr/bin/lilypond", line 1028, in ?
        files_found)
      File "/usr/bin/lilypond", line 693, in make_html_menu_file
        fs = filter (lambda x: re.search ('.%s$' % e, x), rest)
      File "/usr/bin/lilypond", line 693, in <lambda>
        fs = filter (lambda x: re.search ('.%s$' % e, x), rest)
    NameError: global name 'e' is not defined

and no .html is created.

My system is debian sid.
My tex is up to date before two or three weeks.
The lilypond-version is 2.2.6, and I can't remember any problems with
installing it.

I don't know what to do to fix the mistake.

Can anybody help me, please?

Best Regards           Roland
