Error "Could not generate JSVars" on new installation

[lslawski]

I installed Indico 1.2 on a Debian 7.6 following the instructions on http://indico-software.org/wiki/Admin/Installation1.2. I had to change the "Options None" in the Apache configuration to "FollowSymLinks?" to at least get the start page.
After another try I received two error emails by the system. The first one saying

Can you help me to fix this?

Can you please move this discussion to the mailing list? This seems like more of a configuration issue to me.
Otherwise, it would be interesting to see what is the other error.

I suggested a configuration issue at first, too. But after installing Indico 1.1.2 successfully with the same configuration settings (and index.py instead of indico.py in apache conf) I am sure it has to be something else. Hopefully someone on the mailing list can help me.

The error does not occur anymore after granting write permissions on /usr/local/lib/python2.7/dist-packages/bcrypt-1.0.2-py2.7.egg/bcrypt. Thanks to Sebastien Medard from the mailing list!
