[typo] Guid has already been taken - Typo trunk/Rails 0.14.4

[Tom Wilcoxen]

I've just upgraded to trunk typo and edge rails. I ran rake migrate
and it seemd to complete ok. Everything seems fine until I tried to
create a new article, then I get an error:

1 error prohibited this article from being saved
  There were problems with the following fields:
  Guid has already been taken

Is there something I can reset in the database? Most of my articles
have a GUID of NULL, except one that I published yesterday that has
"6ef482f9-bc18-4359-a3c9-fd9a3df55306".

I've tried canceling and creating a new article, but same results. I
looked at the article model, and see the 'validates_uniqueness_of
:guid'. I see the before_save call to :create_guid and the TypoGuid
module which has the create_guid method. In there, there's a reference
to UUID, but uuidtools isn't required -- could that be it? Or any
other ideas?

Thanks!
-Tom
