Hi,
while I read Sjoerd's email, I had an idea that turned out to solve this 
  issue (for me at least).
I remembered that I had played a long time ago (maybe before v.6, for 
sure before v.7) in an init.m file, which resides in my case at

$UserBaseDirectory <> "/Kernel/init.m"

in this file I had a line

Needs["Graphics`"]

which I commented out.
Now all works fine, and all methods of the Histogram function of v.7 
work nicely.


Cheers,
Claus
