The business meeting was canceled at the last moment (we call it
DOTA-CAN in Japan) and I was able to have time to do it.  I
attached the patch for a temporary repair.  It should be
inspected by authorities since I'm not familiar with w3mmee and
forms.

I confirmed the same error occurs with w3mmee and emacs-w3m
while rendering the following page:

http://www.landtag.sachsen.de/slt_online/de/infothek/kopf.html

Tape buttons appear at the bottom of the page and one of two
cancelled buttons causes that error.  Here it is:

<pre_int>[<input_alt hseq="14" fid="0" type=select name="navigator_selectbox" selectnumber=0></input_alt>]</pre_int>

Strangely, those buttons don't appear in Firefox.  The patch:
