In regard to bug #198167 I just received an email telling me that it's blocking bug #216882. I tried to view bug #216882 but was told "You are not authorized to access bug #216882.". If I'm not authorized to access the bug then I should not be receiving email about it. In fact I probably shouldn't even see that my bug report is blocking such a bug.
Thanks for the bug report, and you're right. I'm going to have a look at it, and am going to see what's the case UPSTREAM, but it's likely I'll have to close it as either NEXTRELEASE or DEFERRED.
