By the way, if it is a regression, and you do make a bug report, it'll be a lot more likely to get looked at if you can specify the specific revision which broke it. The fastest way to find this out is to download a build about halfway between r7000 and 4.0-1351, test that, and if it's broken, test a build halfway between r7000 and your middle ground test build etc. This will save you a huge amount of time, even though there are thousands of commits in that interval.
