Quite possibly it is a bug in PBGetCatInfoSync (which is used by 
ScanFolder in the guise of GETCATINFO).
You could try adapting "ScanFolder FSRef" on the FB4 CD Examples to 
your needs. It uses a different method --FSGetCatalogInfoBulk instead 
of the antiquated PBGetCatInfoSync --- and is unlikely to suffer from 
the same bug.

Note that you will have to comment out the definition of FSpMakeFSRef 
in the example file.
