This nicely broke the site for a few minutes after I briefly enabled, then re-disabled LocalisationUpdate:
Sep 22 21:38:22 10.0.2.250 apache2[13018]: PHP Fatal error: LocalisationCache::isExpired() [function.LocalisationCache-isExpired]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "LUDependency" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /usr/local/apache/common-local/wmf-deployment/includes/
As a temp workaround I tossed an LUDependency stub class definition into CommonSettings and ran a cache rebuild to eventually work them all out of cache.
We need to gracefully handle dependencies that can't be restored from the cache.
