How did you install ktorrent ?
I installed it via synaptic package manager. After I tried it and it crashed on me a couple times, I went to the official site and grabbed the source and built it from source and installed it. I was still getting the crash. I have since installed it again via the package manager. This last install seems to have reset my settings along with installing the program and now the crash is not happening :/ .
It's probably caused by loading plugins of an older version which links to a different version of libktorrent
