Version: (using KDE 4.0.0) Installed from: Ubuntu Packages OS: Linux Kate/Kwrite work fine, but give this error message when closing the application (!only on close): KDEInit could not launch '/usr/lib/kde4/bin/kwrite'.
Also sometimes it opens the file again after close and showing the error.
Were you opening some text file from Dolphin? If you were doing it, this bug may be related to bug 164864 (and bug 165590) . Can you still reproduce it ?

I don't experience this anymore, I'm using now KDE 4.1.2.
