Using latex2html-2012-4.fc20.noarch on Fedora 20 Linux with
texlive-2013-5.20131226_r32488.fc20.x86_64, the following file compiles
with latex (and looks fine as a DVI) or with pdflatex (and looks fine as
a PDF), but fails to compile with latex2html.

          v_j &= 
            1 & \text{if this happens} \\
            0 & \text{otherwise}

The tail of the output when it hangs is:

        Writing image file ...
        This is pdfTeX, Version 3.1415926-2.6-1.40.14 (TeX Live 2014/dev)
         restricted \write18 enabled.
        entering extended mode
        LaTeX2e <2011/06/27>
        Babel <3.9h> and hyphenation patterns for 2 languages loaded.
[hangs here consuming 100% of a cpu]

        ^C! Interruption.
        <to be read again> 
        l.163 \lthtmlcheckvsize
        LaTeX2HTML shutting down.
Any suggestions?
