aliases created with wrong case setting

Firstly, let me say this is a great module to have, well done emackn!

But onto the point of this post: it seems the aliases that get generated ignore the pathauto setting "Character case: Change to lower case". Looking over the code, the views_alias module rightly relies on the pathauto_cleanstring() to get the clean term value, but for some reason this function doesn't run any of the case conversion stuff (looks like it gets done in pathauto_create_alias() though).

So is this a pathauto or a views_alias bug? Whatever the case for now, I've written a little patch for views_alias (will attach in next post with correct issue number).
