I cannot.

This is *very* unlikely to be a bug.  People should always exercise a 
great deal of caution about conjecturing bugs when they encounter a
phenomenon that they don't understand.

What do you see if you simply do "ls()"?  (After loading spdep.)
I.e. do you see an "x" listed as an object in your workspace/global 
environment?

What does find("x") return?

It puzzles me that your sessionInfo() doesn't show something like:

There are probably other issues that you have not told us about.

cheers,
