Yep; that's a bug.
Workarounds are easy:
   \newcommand{\idxbeg}{ 0}
   \newcommand{\idxbeg}{0 }
   \newcommand{\idxbeg}{{0}}
all of these work and at least one should not upset
normal LaTeX usage.

A *proper* fix is to change one line in the  latex2html script:

Near the end of subroutine block:
  sub substitute_meta_cmds {

change the line
    elsif ($this_cmd) { push(@pieces, $this_cmd) }
to become
    elsif ($this_cmd ne "") { push(@pieces, $this_cmd) }
or
    elsif (!($this_cmd eq "")) { push(@pieces, $this_cmd) }

Now the conditional will also catch a string of '0'.

Thanks for reporting this glitch.
