[help-texinfo] Overfull vbox in Concept Index leads to a blank page in the middle of the index

[Robert Weiner]

Hi:

I am finishing a Texinfo manual and getting this one error where an overfull vbox in TeX causes a blank page in the Concept Index.  I don't see anything wrong with any of the index entries but the problem always occurs at the same spot in the index.

Could someone have a look at the .log file and suggest how to fix this so I can get this published?

Thanks so much.  The .pdf is in there too and the blank page is around page 118.  I welcome any other formatting feedback as I am only of medium skill with Texinfo.

The .texinfo files and temporary files are all in this gzipped tar archive here:
