I have absolutely no idea of where this bug could be in qbittorrent's code. I will try to ask libtorrent author in case he has an idea (could likely be in his code).
a gdb backtrace would also be more than welcome :) Did you compile it yourself or did you use packages?
Would you be able to recompile libtorrent with debug enabled?
What version of boost are you using?
