Comment 2 for bug 418598

The syntax error looks like a problem with pylint, which is kind of in a sorry state. The pylint dependency isn't important though; it only helps keep the code clean, it's not essential to Mailman's operation.

The two test failures are real bugs. I've seen the 'dict changed size' problem before, though it's difficult to test deterministically (I still think I have a fix for that). The other one I've not seen before, but will look into it. It could be a locale problem.
