[R] Conflict between 'nlme' and 'methods' on R-1.5.0 ?

Hi there!
I use R with the packages 'nlme' and 'methods'.Upon upgrading to R1.5.0, I got the following 
message when loading nlme (after having loaded 'methods'):
The following object(s) are masked from package:methods :

 After that, when I use my class definitions and scripts(which worked fine in 1.4.1) I get the 
following error message when a new("class") expression is used:
Error in initialize(value, ...) : no applicable method for "initialize"

Clearly the problem arises because 'nlme' contains an 'initialize' function, as does the new 
'methods' package.Is there any workaround?
