QImage load error on tiff tiled with lzw compression

Got an error (foo: Can not read scanlines from a tiled image) when trying to load a tiff tiled indexed color image width lzw compression. This only hapens with indexed color files (pl. see attached image), not with RGB color.
Used a work around by creating an untiled and uncompressed temporary file with a system call to "tiffcp.exe" from libtiff library tools.
However, this is a not acceptable consuming time task.
