Version:           2.1.3 (using KDE KDE 3.5.4)
Installed from:    Slackware Packages
OS:                Linux

while uploading/downloading ktorrent 2.1.3 randomly crashes without user intervention. I have the most recent version installed for Slackware 11.0 
The prior version didn't crash.

This is the backtrace report I got for the most recent crash.

------------------------------------------------------------

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.
