Okay, I will apply those patches this evening (objections, Bernd? Arrgh, 
okay your network connection, I remember ;-).

Btw.:  Did you notice that opening a folder the first time in the 
DocViewWidget (e. g. 'qt') is very time-consuming. What do you think 
about indexing the entire DocViewWidgetTree when the Doc-Browser is 
selected the first time. That would increase even the searching-speed.
Just an idea - what do you think about it?

Bye,
