Comment 2 Denis Fateyev 2016-09-11 13:37:35 UTC 
This bug relates to a different project [1,2] which is also known as "Rasterbar Libtorrent". That project has nothing to do with Libtorrent by Rakshasa [3] which is provided by "libtorrent" package. The projects name similarity can be confusing indeed.
