RelStorage and plone.recipe.zope2instance: UnboundLocalError

Yesterday I was experimenting with RelStorage and ran into an error: “UnboundLocalError: local variable 'blob_storage' referenced before assignment.

Although I’m a bit ashamed to admit my mistake, I already made a fool out of myself by opening a bug report about it. So I figured I just as well might help out someone else with a blog entry.

The cause of the error is pretty simple. I still had the zeo-client option in my [instance] section set to true. The solution is thus equally simple: just set it to false.
