No, it gives a *warning* and returns NULL.

Ooops, bad example.
Try this instead:
a <- ts(runif(6500), start=0, freq=10)
b <- lag(a, 1)
c <- ts.intersect(a, b)

Gives an error from .cbind.ts

A workaround would be to convert both a and b to zoo class,
intersect them using zoo's merge and convert back to ts:

library(zoo)
z <- as.ts(merge(as.zoo(a), as.zoo(b), all = FALSE))

Regarding your other question,

Sys.putenv(LANGUAGE="en")

will result in error messages in English.
