A dialog box appear with the following text when i try to launch kdevelop 4.1 in KDE 4.6: "The installed Kate version does not support the SmartInterface which is crucial for KDevelop up to and including version 4.1. To use KDevelop with KDE SC 4.6, where the SmartInterface is replaced by the MovingInterface, you need KDevelop 4.2 or higher."
