Well, it's nothing to do with QT anyway.  I added low-level opendir()
and readdir() calls, and these are returning invalid details for the
non-ascii entries.  This is only happening when the application is being
run via "su" in a login shell (su - USER) though, when run as a
non-login shell (su USER) then it works fine.  My test application works
fine in either case though, so there's obviously something more complex
going on.
