Description Andrej Nemec 2016-06-07 08:31:01 UTC

Comment 2 Denis Fateyev 2016-08-10 20:43:48 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.
