I cannot load Juk, it segfaults on every start.  The segfault occurs right after a dialog telling me that it can't find a certain directory (initially this dialog did not cause a crash).  It seems to be fixable by deleting .kde/share/apps/juk/cache.  It's also fixable by recreating the missing directory.
