[TxMt] Blogging bundle oddity

I just experienced a wierdness with the textmate blogging bundle.

When I tried to fetch a post from my blog to edit, it retrieved the post which was the one above the one in the dropdown list before the one I selected.

I just did a little experimentation, and it looks like the problem occurs when I select a post which was posted before a duplicated post which I deleted. So, schematically, the list shows:

Post 10 Post 9 Post 7 ...

Where there was a Post 8 with the same name as Post 9, but it's now gone.

Selecting post 7 from the list brings back the deleted post 8.

The blog is implemented with typo.
