kvazaar allows to create files with dependent_slice_segment_flag == 1;
but it puts one row into one slice and so the above issue would probably
not manifest itself. The caveat "probably" is necessary, because
decoding such files with slice threading leads to "entry_point_offset
table is corrupted" errors (which is probably a decoder bug).
