Chm2pdf fails to process chm's without table of contents

[Max]

Greetings!!!

An example of file without toc is at http://dl.dropbox.com/u/7033680/chmtest.chm.
When trying to convert it by chm2pdf:
chm2pdf --continuous --verbose --verbositylevel high chmtest.chm.

No pdf is generated and here is the output:

rm: cannot remove `/tmp/chm2pdf/work/chmtest/*': No such file or
directory

I've modified chm2pdf script so that it now creates pdf files for chm files which contain no table of contents. You can get my modified chm2pdf at http://dl.dropbox.com/u/7033680/chm2pdf. Developers, if you are still here, please check if it worth to update chm2pdf with this fix.
