The window shows for about half a second, and then goes back to the crash screen.

Version ?

Did you get a KDE crash dialog ? If so it would be really handy to see the backtrace.

ktorrent (the process) keeps running but the GUI window closes RIGHT after opening, I barely even have time to see it.

I tried cleaning and removing ktorrent, I removed the kdr/share/apps/ktorrent folder, I removed the one in usr/share/apps too, but it still does the same error on when I start it :

nairod@nairod-serv:~$ ktorrent

important note : it runs fine on my girlfirend's account on the same computer.

I cant see which version number it is from here but its the latest version downloadable for Ubuntu festy fawn 7.04

thanks in advance

It is probably still running.

In a terminal type : killall ktorrent

Then remove ~/.kde/share/config/ktorrentrc

And restart ktorrent
