Thank you, Mark, for the report.

Indeed --- to my own very big astonishment --- 
I *can* reproduce the problem.

In the above messages, it's pretty funny that
"dgCMatrix" is said to be a virtual class (which it is clearly
not from the Matrix source).

The "daily" CRAN package checks don't show the problem yet,
but the checks' R version is

>>  R 2.7.0 Under development (unstable) (2008-01-27 r44199)

which is a bit older, than the one you used 
(and even older than the one I used ..... r44258)

I'm pretty sure I know around where the problem appeared..
More on this later.
