[Rd] Bug in loadNamespace?

Looks like this could be locale related. Both of you are using non-US locales, and Sys.setlocale is not changing the last entry (LC_MESSAGES), which is as documented, but maybe somehow related. 

I can reproduce with

Peters-iMac:r-release-branch pd$ LC_ALL=da_DK.UTF-8 BUILD-dist/bin/R --vanilla

R version 3.2.1 beta (2015-06-07 r68485) -- "World-Famous Astronaut"

Type 'q()' to quit R.
