Spurious warning in as.data.frame.factor()

Hi,

The acrobatics that as.data.frame.factor() is going thru in order to 
recognize a direct call don't play nice if as.data.frame() is an S4 
generic:

 ??? df <- as.data.frame(factor(11:12))

 ??? suppressPackageStartupMessages(library(BiocGenerics))
 ??? isGeneric("as.data.frame")
 ??? # [1] TRUE

 ??? df <- as.data.frame(factor(11:12))
 ??? # Warning message:
 ??? # In as.data.frame.factor(factor(11:12)) :
 ??? # ? Direct call of 'as.data.frame.factor()' is deprecated. Use 
'as.data.frame.vector()' or 'as.data.frame()' instead

This spurious warning showed up on the recent Bioconductor daily build 
reports after we've updated the build machines to the latest R devel. 
It's causing some confusion and breaks at least one unit test.

Thanks,

H.
