What's that '+' sign at the end of the path?

I'm using en_US.UTF-8 on Ubuntu 8.10 and it seems to work for me.
The regexp does look funny: there are non-letters included in the
range and it may be that different versions of egrep are more or less
strict in checking it. I would change the texi2dvi script to use [A-Za-z]
and submit a bug report to texinfo.

You can always change the LOCALE just for the texi2dvi invocation.
I believe that the following works (untested):
LANG=C texi2dvi ....
or maybe
LC_ALL=C texi2dvi ...
