Thanks to Lixinyu, in the first place, for reporting the problem, and also thanks to Richard for reviewing and incorporating this patch into his queue for 5.0. I also think, as Richard does, that this should go into 5.0, even in this final stages.

Happy Easter, or hapy and sunny weekend, whatever you choose.
