I have Ubuntu 10.10 64bit, qBittorrent v2.8.0 beta4 and libtorrent-rasterbar6 v0.16.0

[Christophe Dumez (hydr0g3n)]

It seems to be a libtorrent v0.16 issue, I forwarded the bug report there:
http://code.google.com/p/libtorrent/issues/detail?id=188

libtorrent v0.16 is still unreleased so it is not surprising if there are still some bugs here and there. However, it does bring uTP support and a few other goodies and having it in my unstable PPA is a great way to debug it. I will package a new SVN snapshot as soon as the bug gets fixed. Thanks for your report.
