"Could not load plugin at path (null)"

[elia]

After the installation worked, but as I restarted the app keeps logging out from the Campfire account. Seems that it can't load the plugin since I got this message in the Console app:

... (same as above x13)

Or, something may have dirtied layout in the middle of updating it.  Both are programming errors in Cocoa Autolayout.  The former is pretty likely to arise if some pre-Cocoa Autolayout class had a method called layout, but it should be fixed.
