Hi,

I have a local setup problem on my Linux that let Python tests fail. For
some reason, it cannot write to /tmp/ file... (see error message below).

I can resolve the issue with "sudo rm -rf /tmp/*", but this raises other
problems on my system. Furthermore, the testing problem is back, after
restarting my machine.

Do you have any idea, what I need to do, to get my configuration right?

-Matthias
