That appears to be similar to this bug, which has been fixed in R-devel:

https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17558

That fix only handled the case of an example using data() with the 
package argument set to an expression, not a constant string.  Does one 
of your examples do that?  Other possible functions which haven't been 
fixed are "library", "require", "loadNamespace", "requireNamespace".  If 
you use one of those in an unusual way, that might be the cause.

If that doesn't help, I'd be willing to take a look at the tarball to 
see if I can spot what's going on.
