Failure in tempfile.mkstemp

Guys

I keep getting this error and have to delete the install to get it back up and running. Here is the error from the log file:

2011-09-17 21:15:58,630::INFO::[__init__:760] Traceback:

This usually happens when there is over 10gb of files to download. The OS is NAS based (Netgear Stora). Any clues appreciated!

Is /home this right place to store the "incomplete" folder?
I assume you bought python and SABnzbd from here:

If so, please ask the question there.
