I can confirm that reverting 528ea798f02... fixes the problem for me.

OK, that makes sense.  I hadn't had any problems with it, but it could
be v. dependent on how your system is configured.

Does "git revert -m 1 528ea798f02ccb03023e72cbda665ed5c3eec6b1" and
rebuilding fix the problem? If so, I'll revert it in stable until we can
sort it out.

Dongxiao, can you investigate this?
