As i expected, there is a race condition.

By the time ppmquant gets the file input, the file, actually the
/tmp/l2h* directory, has been already removed, resulting in the
above it seems.

Do "ktrace -di -f log latex2html file.tex ; kdump -n -f log | less".
Then search for string "/tmp/l2h".  You will see that directory is
removed well before ppmquant get to do its thing.  (Mind that i have
not checked if any of the file handle(s) is retained, or retained
file handle is not closed, before directory removal.)

 (In that case, IMO, it would not be a race condition but an
 indication of bad design of latex2html.)

Yes, see above.
