The optimization engine has in R 2.2.0 changed, with mixed results, see http://finzi.psych.upenn.edu/R/Rhelp02a/archive/64096.html In the short run, setting pnlsTol to a large value than the default worked for me sometimes. In the long run (hope I got Douglas Bates right) you could switch to lme4 which is work in progress, but currently it cannot handle your case.
