[BioC] problem with justRMA in 2.10.0

[Fraser Sim]

I'm getting a cryptic error message when trying to run justRMA on a folder
of files, with the file names specified in celFiles. I am not setting the
phenoData or protocolData at this point and just want the eset populated
with the default pData. This code worked fine under 2.9.2. Thanks, Fraser

Here's my code:

> library(affy)
> eset <- justRMA(filenames = celFiles)
Error in validObject(.Object) : 
  invalid class "AffyBatch" object: 1: sample numbers differ between
phenoData and protocolData
invalid class "AffyBatch" object: 2: sampleNames differ between phenoData
and protocolData
