I am getting seg fault when I am opening project in QT under KDE. Error is:

QtCreator(20093)/ findLibraryInternal: plugins should not have a 'lib' prefix: "libkfilemodule.so"
QtCreator(20093)/ KPluginLoader::load: The plugin "libkfilemodule" doesn't contain a kde_plugin_verification_data structure
kdeinit4: Communication error with launcher. Exiting!
kdeinit4: Communication error with launcher. Exiting!
Segmentation fault (core dumped)


I also tried creating softlink:
ln -s libkfilemodule.so kfilemodule.so, but still getting the same problem.
