No; please do "report" the problem, which may be useful for development, but please do *NOT* use the bug repository, and probably don't assume it's a bug in R, unless you have quite a bit experience about R bugs and non-bugs.

Instead, just send e-mail to R-devel and explain, and you may actually helping R development, particularly if you are willing to investigate some details that we ma ask you about.

Too bad.
It might have been interesting to see what

 replicate(100, mean(rexp(10)))

or also

 hist(replicate(100, mean(rexp(10))))


gives on your R-devel installation.
That's why Brian Ripley helped you by mentioning 'set.seed(1)'.
