Personally I think its related to a code splitting bug that has been fixed in GWT 2.6. The bug causes the GWT compiler / code splitter to not emit some needed defineSeed() statements in split points. The symptoms mentioned in the below issue/discussion are not 100% your symptoms but I think it is somewhat related.
