The error comes using the  Biobase Version: 1.10.0. Everythink run 
smootly if I run the same commands on Bioconductor 1.7 installed under 
R.2.3.0

I was expecting that there should be some sort of back compatibility 
with  at least the previous release of the exprSet. There is any way to 
convert old instances of exprSet in the new one?

I think Martin already responded to your question as you posted it on
the bioconductor list.  So for the archive, please look there:

The issue of dealing with serialized instances of classes when the
definitions of those classes get updated is a difficult one.  We have
some improvement in the devel version of Biobase that should go a long
ways to easing these issues.  For the interim, we will try to post a
helper function that you can use to update your saved data sets.

Best,
