How did you update? This error usually only happens when the plugin files are no longer existing.
Did you extract the new version over the old one, keeping all existing files? This is how an upgrade should be performed, you should never have to delete/move any files...
Check the serendipity_plugins table, all the plugin directories/files with the ID that are contained in the output seem to be missing, which is why it only says "Error"...

I gave it a second try, extracting by hand in the plugins directory, et voilà, all fine -- that's a real noob mistake replacing the whole plugin directory. Sorry and thanks.
