emoticon graphics missing

Binary package hint: evolution

I can not use emoticons in evolution via keyboard short cuts. I get empty little squares with an "x".
This happened after I upgraded from Ubuntu 6.10 to 7.04. I have autoremoved and installed evolution and have even let
synaptic package manager do it for me. The emoticons have not returned. The list is still in the menu but they show the wrong emticons. As an example laughing is now sad.
