The symbols are truly weird... However this is a translation problem,
because in Windows/Mozilla this will give you a normal SUM-symbol with
correct parameters.

Thx. I already tried that (cause Google is my friend), but it didn't help.

After doing some hours of research, I discovered that there is no Type1 font 
encoded to render ISO-8859-1 symbols. Therefore ISO-10646 is used to translate 
the symbols. That causes partial wrong rendering.

I found a nice document: http://silas.psfc.mit.edu/tth/symfontconfig.html , 
which exactly explains the complication. 
There is also a script provided ( 
http://silas.psfc.mit.edu/tth/symfontconfig.tar.gz ), which solves the problem. 
Now all mathematical symbols are displayed right and I am happy.

Maybe I should write a bug-report or something..
