Yes, if you use a broken PDF viewer (you have not told us yours). From 
?pdf

useDingbats: logical.  Should small circles be rendered _via_ the
           Dingbats font?  Defaults to true, which produces smaller and
           better output - this is provided for those who insist on
           using broken PDF viewers.

I get the problem in evince but not acroread in F10.
