[Rd] weird warning in [.data.frame with 2.10

I'm getting the following warnings under 2.10 v50082 but not v49613

>> In addition: Warning messages: 1: In `[.data.frame`(df, -(1:nrow(df)), , drop = FALSE) : named arguments other than 'drop' are discouraged

5: In `[.data.frame`(object, !omit, , drop = FALSE) :
>>   named arguments other than 'drop' are discouraged

In neither case are there any named arguments, as the messages themselves point out.

The errors are popping up while running my 'debug' package. They are associated with another sporadic new warning nearby about "number of items... replacement length", which is more of a direct worry. This has never happened before in 'debug'; it makes me think that something more sinister may be going on in the bowels of R, but I haven't tracked it down clearly enough to report it.
