Hey Aurélien!,

The problem seems to be the parameter "shell" in the way of calling the
subprocess.call method.

I haven't used subprocess before, so I read a little bit about it in PEP 324

With subprocess.call(), this would look like:

          subprocess.call(["stty", "sane", "-F", device])

      or, if executing through the shell:

          subprocess.call("stty sane -F " + device, shell=True)

I use debian 5 lenny, python 2.5.2. The graphs works for me without the
shell parameter. e.g.

 if target != 'dot':
            if mapfile:
                subprocess.call([self.renderer,  '-Tcmapx', '-o', mapfile,
'-T', target,
                                        dot_sourcepath, '-o', outputfile])
                subprocess.call([self.renderer, '-T',  target,
                                         dot_sourcepath, '-o',  outputfile])
        return outputfile

Do you think this has something to do with the python's version?

Thank you very much for your support!
