What version are you running?
ReviewBoard 1.6.1
Apache and mod_wsgi
MySql
Python 2.6.5

What's the URL of the page containing the problem?
http://reviewbd/reviews.wae.com

What steps will reproduce the problem?
1. Attempt to install on Ubuntu 10.04.3

This appears to be some kind of Django or mod_wsgi issue, but I've tried re-installing with no luck.  The only questionable part of the installation seemed to be the install of pycrypto -- I started with version 2.3, but then dropped back down to 2.1 after seeing that users had issues with newer versions.


What is the expected output? What do you see instead?
Initial screen displays "Review Board is taking a nap" message.

What operating system are you using? What browser?
Ubuntu 10.04.3
IE 8 browser

Please provide any additional information below.

I got the same with one extra line (?) in the error.log:

File does not exist: /var/www/reviews/htdocs/media/rbcommons
#2 andrew.se*********@gmai***** (Google Code) (Is this you? Claim this profile.) 
I had the same issue. 
The root cause of the issue: the module pycrypto on your Linux box is old and does not contain the function Random.
I upgraded the pycrypto module and issue disappeared.

Try to upgrade pycrypto module:
easy_install --upgrade pycrypto 

and restart apache after that...
