This is my fault.
There is an unchecked 0 pointer in DoctreeGlobalConfigWidget. Additionally 
doctreeview needs many changes for the new config-api. It is currently wrong 
to read project dependent options in the global config dialog.
Unfortunately i will only have time for the restructoring from next weekend 
on.
