What version of python-markdown is installed? And what version of Djblets?

Can you give beta 2 a try?

Note that we really do not recommend using beta releases for production installs, as we can't offer any timeframe for fixes, nor any guarantee of stability. However, in this case, it looks like an installation issue or version compatibility problem. Knowing the versions above will help determine that.

This is with Markdown-2.4 and Djblets 0.9beta1. Reviewboard was installed using 
easy_install -d lib/python2.7/site-packages -f http://downloads.reviewboard.org/releases/ReviewBoard/2.5/ -U ReviewBoard

I just ran this command again but it still takes the 2.5b1. Any idea how I can force the b2?

Can you show me the entire output when running that command? Also, what version of easy_install? You may need to upgrade that (the Python packaging world has sorta recently standardized on new versioning naming that we're forced into, and it results in compatibility issues with some older tools).

Output of that command is pasted below. easy_install has version distribute 0.6.24dev-r0 . We upgraded reviewboard because of bug #3928 (which is actually a chrome bug). 

I tried to update ReviewBoard to b2 using the egg file which required Djblets>=0.9beta2. I installed that but then easy_upgrade still couldn't find it. I suspect its because beta2 vs b2. It indeed sounds like our easy_install is too old. For now, we'll just downgrade reviewboard to stable version since that worked fine for us. Thanks for looking into this.

If you downgrade, you must restore to a database from before the upgrade, or you're going to hit versioning problems later when upgrading again.

It is an easy_install problem. That version is very old. You can update it with:

    sudo easy_install -U setuptools
