Sorry if this is a duplicate...sounded similar but different to all other issues here.

Views that take url arguments are overriding the sub-paths for me...

ie if I have blog/[username-argument]/[node_title] as my node alias,

and a view at blog/[username-argument] that displays all posts by that user,

then going to blog/[username-argument]/[node_title]/edit goes to the view, rather than the edit page.
