  (Sorry about the mangling of the example format below.)
  I very strongly suspect that this is due to a mismatch with
the version of the Matrix package.  Version 1.0-5 is available
on CRAN; could you please install it (either via update.packages(),
or via install.packages(), or via the appropriate menu item
if you are running in a GUI -- they should all be equivalent)
and report back if the problem persists?
  
   (The listed dependency of the package is only
Matrix >=0.9996875-1 ; we should probably update this, although
we are also working hard to replace the current version of lme4 ...)
