received a chunk that has already been filled

Left this on rtorrent , but it looks like it might be in this library instead:

Caught internal_error: FileList::mark_completed(...) received a chunk that has already been finished. [#34BF0C062F8728B8A16ED5FF9A925548A6A2B0C8]

Seems like this can be triggered and re-triggered when this torrent is hash checked , or started.
