I thought this had been fixed in the 3.02 version?
Knew it was present in 3.0, but not 3.02...
Yes, I just checked a scene I made a while back that was infamous for this 
particular error and it didn't show just now when I tried it again (had to be 
sure).
So check your version and please let us know if it's 3.02. If it's 3.1 maybe 
make a posting in the bug report area.
