That error seems to be coming from newerVersion in old.packages, and means
that an installed package has an incorrect Version: field.  Try

installed.packages()[, c("Package", "Version")]

to see what it might be.   (Actually, it could mean a CRAN package
has an incorrect version, but then lots of us would see it.)

You might want to use traceback() to confirm the source.

Wait for 1.3.1 and try again.  These problems usually come from packages
installed a long time ago without valid version information.  The newer
(1.3.1) tests for outdated packages wrap the comparisons into try() and
hence no longer throw an error ...
