bug in methods' 'initialize' (or the functions called in turn) ?

Hi,

I experience a very strange behaviour when trying to instanciate a S4 
class. A call like 'r <- new("MyClass", foo="bar")' returns apparently 
cleanly, but in fact a subsequent use of 'r' results in a 'r does not 
exist error message'. After a bit of hunting with 'debug', it seems that
the bug is in 'initialize' (or one of the functions it calls in turn).
All this while using R-devel from Nov. 16th (R-2.0.1-devel).

I did manage to make a simple example to reproduce the bug, but to do so 
one needs few packages from the bioconductor project. If this is not yet 
know and one shows interest, I can provide the few lines of code needed 
to reproduce it.

Two points:

a) yes, please alsways specify a simple reproducible example when 
talking about a "bug";

b) if this "bug" does not appear in R-2.0.1 but only in the current 
R-devel, it might be worth to wait a couple of days. Perhaps someone is 
including some new functionality and has not yet finished the updates.
