After moving a page to a new location that contains a space, the 'revert' link will not have the space converted to an underscore which will cause the visible revert link to contain the last part of the url and the target to contain the beginning only, effectively making the link useless and breaking formatting.
This is a broken customization to the default message, which doesn't include any revert or other links at all. Nothing to do with us, tell enwiki admins to fix it.
(Note that it may not be fixable to its old state, due to bug 6261.)
