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

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)'.
