I also started a thread on ktorrent.org's developer forum about this bug here: http://ktorrent.org/forum/viewtopic.php?f=1&t=4044&p=20275#p20275 Cannot seem to reproduce. Could you run it under valgrind ? valgrind --log-file=vg.log --num-callers=50 /usr/bin/ktorrent --nofork When it crashes, post the vg.log file here.

Did you also compile and install libktorrent 1.1 ?
Yes, I compiled and installed libktorrent 1.1 first. Is an older version of libktorrent still installed ? Yes. I have the 1.0.5 libktorrent installed. It is the official ubuntu package, so it is not in /usr/local. When I compiled the new version of libktorrent and ktorrent itself I made sure the path setting was /usr/local when I ran cmake for both of them. That should prevent any confusion, correct? Things could get hairy with the plugins. Try uninstalling libktorrent 1.0.5, and see what happens. Looks like that fixes the problem. |
