In MW 1.19 it fails under some circumstances due to a not-declarded dependency to mw.user.anonymous(). Patch follows.
Created attachment 9902 [details] Add a dependency to /mediawiki/trunk/extensions/CentralNotice/special/SpecialBannerController.php Add a dependency to /mediawiki/trunk/extensions/CentralNotice/special/SpecialBannerController.php I think that's the most fast solution: Until the callback, other gadgets might have loaded the mw.user module and further deferring the XHR by waiting for mw.user might not be the best. Evaluate yourself.
Fixed in r109977. Thanks for the patch!
