It probably means that this isn't a TIFF file that you are trying to
read. Who knows why? Try this code:

isTiff = Query_Tiff(ifname, fileInfo)
IF isTiff THEN BEGIN
dims = fileInfo.dimensions
ns = dims[0]
nl = dims[1]
ENDIF ELSE BEGIN
Print, 'Problem file: ', ifname
Continue
ENDELSE

Cheers,

David
