Hmm, I haven't been able to reproduce this.  Can you try calling
traceback() after the error message appears and sending the output?

Also, if you are able to share the data, I could try reproducing
here.  If the data is sharable, perhaps you can save the exset object
using save() (and compress=TRUE)  and post it on a web/ftp that I can
download from?
