IIUC, this got completely solved with these commits:
* Generate better validation error message when using name regexes
923cf20eca35b551ae1fb4a77835f8104ea6cbed
* build smaller name regexes for validation
f467af7c55af7807603e77effd709a53fba9b8dd
* add regression test for bug #1541691
243d543f0fc3071a29052b1edf65a262e10647b8
I'm going to double-check it on current master (Newton) code.
