Do you mean 4.0-1202? r1202 refers to ancient builds back when Dolphin used SVN (and the code was closed source? I wasn't here during that time so idk). But yes, every build since 4.0 that comes from the build-bot is based on 4.0, plus the many, many changes that have since been made to that release.
My advice is to find the exact revision that causes this issue for you. Look up how to bisect revisions (google it), then start testing to find out what change brought about this problem.
