We had a similar problem with Shiny - some notes I had from a chat
Winston follow:

We seem to be getting a bug related to this for some people who are using Shiny
https://github.com/wch/r-source/commit/5c97cd443058434015670f0b7af4c2a86b732e89

setRefClass calls refClassInformation calls .makeDefaultBinding calls
.setDummyField
turns out the problem was that we were distributing a package built
under 3.0.1, and users who installed under 3.0.0 had problems with
something about .setDummyField
The solution seems to be to rebuild under 3.0.0 and distribute that


So it may not be a problem with the package source.
