Kepler

This is with wrp at r23202. I deleted .kepler and KeplerData. I create a trivial workflow (default SDF and RExpression) and save it as a KAR in the default local repository. On restarting Kepler, the KAR and local repository are not listed in the components pane. If I go into Sources and manually trigger a re-build of the component library, I can see the KAR, but nothing happens when I attempt to open it (right-click menu) except an error in the console:
