Seems to be fixed in Git master

(I see you noticed the typo in my original example: b --> a). Agreed, I'm getting this error with an old master. I just tried master and it worked fine, but the maintenance branch ('1.6.2.dev-396dbb9') does still have this issue.
1.6.2 hasn't been kept up to date. I suspect 1.7.0 will be the next release. Chuck
