Please try 1.2.25b in the download area.

Appently the iSeries implementation is sending the NativeFileSystem
field in ASCII (see hex above) even though Unicode is indicated. I
seem to recall Windows 98 doing someone like that too.

Anyway, that field is of no use to anyone so I think it's safe to just
comment out that bit if code.
