can't edit nodes with aliases that start with same string as other aliases

I've come up against a bug with URL Aliases when two node titles start with the same string. This only seems to apply when you try to edit the node. I've posted an issue to the path module, but haven't gotten any response. Unless I'm the only one experiencing this issue, it seems like a rather serious bug. http://drupal.org/node/111775

Here is the scenario:
A CCK node type.
Pathauto enabled and set to create url aliases for node type with "something/something/[title]" as alias.

If the "[title]" has a shared string as another "[title]", you can't get to the edit page through the url alias.

Example:
My Pathauto urls for my node type are, "compass/site/[title]".
I have a node with a title "Seattle" and the url alias "compass/site/seattle" and the edit url alias as "compass/site/seattle/edit".
I have another node with a title "Seattle Center" and the url alias "compass/site/seattle_center" and the edit url alias as "compass/site/seattle_center/edit".

The URL alias for both these nodes works fine, but when you try to edit the second node, it can't resolve the url and defaults to the Drupal welcome page. You can get to the edit page fine if you use the normal node path: "node/478/edit".

Has anyone else seen this and are there any solutions?
