What if /home/150 not readable?

[Sbozzolo]

Hello,

don't ask me why but I've just ended up skimming the scratch code. I noticed this:
sys.path.append("/home/150/scratch").
Therefore the code won't work if the user has no reading permission on /home/150, ie
he's not in the wheel group.

Maybe it's not a bug but a feature, in that case, close this issue.

Bye,
