Pathauto 2 is pretty picky. And a bully. What finally made it happy.

So even as the help text says raw versions are dangerous, Pathauto version 2 badgers you into using [title-raw], [user-raw], etc. So just put that in right away, and it won't yell at you.

The other trick to make Pathauto happy on the first try is that a Blog path (and other node types) does not take [user] or [user-raw]. Instead, you should put in [author-name-raw].

I expect it will get more user-friendly (and export and import of patterns would be really nice) but it's one of the must-have modules no matter what.
