Hi,

It has been some time since I file this issue, it seems somebody 
else also have this issue[1].

After some debugging, I find find-file-visit-truename must be nil 
inside autoload-find-generated-file in order to get the correct 
path.

I haven't found which commit introduce this issue, the last commit 
here is from larsmagne

Maybe he can share some ideas about this issue.
