Yet, when I try to use it, I get something incomprehensible:

Error in str(NLSY) : internal error -3 in R_decompress1 In addition: Warning message: In str(NLSY) : restarting interrupted promise evaluation
That usually means that the LazyData database has been corrupted (and most likely was not created properly). As to why: we need the reproducible example the posting guide asked you to provide.
I had the same symptom a couple of days ago. It went away after quitting and restarting the R session. I kind of put it down to leaving an R session running while updating R (Yeah, I know: Still nothing reproducible...). The warning about nnet from 2.15.3 while installing to R-2.15.2/library suggests that something similar could be afoot in this case.
