@Will: The indicator is unrelated to Nepomuk. It will be started when a directory starts to load and KDirLister will emit a signal when it's finished. In 4.6.1 an issue has been introduced in KDirLister that might be the root-cause of this. This has been fixed a few days later and AFAIK distributions like Suse took care to patch 4.6.1. Everything should be fine in 4.6.2 again.
