  Interesting.  One is 64-bit and the other is 32-bit.
I also see that you have different sets of packages loaded.
I would recommend (1) trying with R --vanilla, to make sure
that you are starting from a clean session; (2) perhaps, if
you're up to it, using traceback() and/or options(error=recover)
to try to track the problem a bit farther; (3) contacting
the package maintainer ...
