When I close KDESVN with the close button in the upper right of the window I receive the following error: Could not start ksmserver. Check your installation. This appears in a grey window (with an okay button) on a black background. If I click okay then KDE returns to the KDM login screen. KDE has crashed completely at this point (along with all running applications).
The Qt4/KF4 version of kdesvn is no longer supported - closing. Please open again if this still happens with kdesvn 2.0.
