 I think the subprocess.Popen call in RUtils is at fault. The
"command" is a list, but I think shell=True causes it to be sent to
the shell as a command line. If you concatenate (join) the command
list with spaces into a single string, this works:

 proc = subprocess.Popen(" ".join(command), shell=True,
stdout=subprocess.PIPE,
stdin=subprocess.PIPE,stderr=subprocess.STDOUT,
                                universal_newlines=True)


line 62 of RUtils.py in the sextante plugin.
