tiff file causing baloo_file_extractor and gwenview to hang
baloo_file_extractor hangs on the attached tiff file, consuming 100% cpu and making no progress.
gwenview does the same.
Gimp seems to be hanging also... So I expect there is something fishy in libtiff.
Over to maintainer of graphics/tiff.
Please report the issue upstream, and let us know if there is a patch.
