Ok, I've looked more closely at this - so you're wondering
about a findfirst request ending up (after smbd/filename.c
processing) with a pathname like :


where the last component is a mangled name ? I don't think
this can happen. The reason is that if the path 


exits, then coming out of the unix_convert() function
the entire pathname will be unmangled. If the path doesn't
exist, then yes the last component of the path will be
left mangled, but then the findfirst should fail anyway
(as the file doesn't exist).

If you have a test case that can show Samba failing under
these circumstances I'd be glad to re-examine this.
