Massimo, I did a fresh install with the new trunk and this is the traceback:

Quoting Jonathan Lundell:

It should be* IOError* (capital E)

---

with that change it works.

Reply 2:

 open('/dev/urandom','r').write(''.join(chr(t) for t in ctokens))

In this line, you are attempting to open /dev/urandom for reading, and then 
are attempting to write to it.

Instead, you need to read the data from /dev/urandom, and then open a new 
file for writing to write your output.

Hope that helps!

what can i do?

I am releasing 1.96.3 in a minute to fix this.

On my Ubuntu 10.04 system /dev/urandom has mode 666 which means read and 
write for everyone. If it is not writeable on Webfaction for others then it 
is either a policy for a different Linux distribution or a policy of 
Webfaction.

The idea behind writing to /dev/urandom is to seed the random number 
generator so the output read from the generator is less likely to be guessed 
which increases security.

[web2py] Re: webfaction: Internal Server Error after upgrade to 1.96.2

[ron_m]

To add some more, on Ubuntu and according to man urandom all major Linux 
distributions since 2000 the file /etc/init.d/urandom saves the random 
number pool into a seed file and restores it on startup by writing it back 
to /dev/urandom.
