Description Alexis Kauffmann 2014-10-23 16:17:25 UTC 
I just start the program, it works fine. After a variable time span, when I came back to check it, it is frozen: does not respond to clicks, ETAs for downloads/uploads do not change, etc. I have to kill the process to shut it down. After that, I can restart it and it will freeze again after a few moments.

Reproducible: Always

Steps to Reproduce:
1. Start program
2. Go do something else - e.g. grab a coffee in the kitchen or open a web browser


Actual Results:  
3.  Ktorrent is frozen!

Expected Results:  
4. It should be downloading, uploading or standing by, ready to use.

Here is the backtrace, generated using DrKonqi (killall -11 ktorrent). I could not submit it via Dr. Konqi because, very strangely, it is not accepting my login credentials - but that is another bug!
