Boudewijn is my first name, Rempt my surname. Same order as with you, in fact.

Ah, cool. I'll check psi  & test my own code then. Thanks for the tip. One 
weird thing I noticed is that unless I instantiate a QTextStream before 
registering the exception handler, it doesn't get registered on Linux.

I think it would be a very useful project for KDE. In fact, I'd wanted to
