[BioC] L-BFGS-B needs finite values of fn error in vsn package

[Isaac Neuhaus]

I have installed R version 1.9 (64 bit compiled) and the Biocunductor 
packages release 1.4 which include the vsn package 1.4.13 and I am 
getting the following error:

data <- ReadAffy(filenames=cels, sampleNames=names, verbose=F)
 > vsn.data <- expresso(data, normalize.method="vsn", bg.correct=F, 
pmcorrect.method="pmonly", summary.method="medianpolish")
normalization: vsn
PM/MM correction : pmonly
expression values: medianpolish
normalizing...vsn: 20000 x 24 matrix (1 stratum). Please wait for 4 
dots: Error: L-BFGS-B needs finite values of fn
Execution halted
