Opening kwrite from a terminal session works fine on my two Pardus 2009 systems. No problem at all. It would be helpful to know if anyone having the problem is seeing any error messages.
FWIW, there are other choices for text editors, particularly if you have the contrib repository enabled. I have mousepad and gvim both installed on my system. I've used vi for about forever so gvim is comfortable to me. Mousepad, from Xfce4, is very lightweight but has less features than kwrite. Pardus isn't lacking choices
