When setup.py check fails

Last night I was about to release a new version of django-flatblocks, when I ran into a weird problem:

$ python setup.py check -r                                                                                                                                                                           [develop] 13:58+0100
running check

The cause of this issue was a bit unexcected: A string in the release notes of a version I had already released about a year ago. So what changed? Probably the Python version but also most definitely the version of docutils I had installed in order to preview the release notes before every release.

So I started downgrading from 0.8.1 all the way to 0.5.x to finally make the check command not die on me anymore.

There is also an issue in Python’s issue tracker which has a patch attached (and committed) that solves this issue. So if you don’t want to downgrade docutils in your virtualenv, this is probably the way to go :-)
