According to your sessionInfo() below you are using R-2.5 / BioC 2.0.
This version of Bioconductor is more than 1 year old and we don't support
it anymore. FYI, the Bioconductor project releases a new version of the
software every 6 months and only the latest release is supported.
Please update your installation to use the current release version
(R-2.7 / BioC 2.2) and let us know if the problem remains. Thanks!
