This bug has not been voted, been the source of a duplicate or otherwise touched in at least six months. With this in mind, I've been asked by the bugmeister to bump this bug's priority down from "High". Concerns can be addressed to mah@everybody.org.
I'm not sure it should fail more graceful. It was specifically made to abort in that scenario. There is probably an underlying bug that needs to be solved instead. If there are multiple versions of a module somehow making it into the registry, other module could break even worse by getting the wrong dependency and what not.
This is the functional equivalent of two pieces of php code in MediaWiki (e.g. core and an extension, or two extensions) registering the same class name in the Autoloader. There is imho no acceptable graceful behaviour. It is front-end, not backend, so you could at most decide to disable the entire javascript pipeline, but that seems not worth implementing for this.
