I'd really like to see the debugger log. Something _is_ unusual here.

And you don't have to. It even says so in the third sentence

 "Using the debugging helpers is not essential"

Debugging helpers are used to e.g. display thinks like std::map as
as sequence of entries, instead of plain C structures containing
pointers, and they _can_ be used to do "really fancy things". Like
displaying image data in an external viewer, or displaying fuctions
in xplot or such.

You do not have to take care of the first case (std:: and Qt containers)
as there are like 80 of such beasts "built in", working "out of the box",
and you can simply ignore the second case if you feel inclined to do so.

Qt Creator won't protect you from knowing what you do. Maybe just sticking to
Netbeans is the best option in this case. You seem to know and like it.

[Well, I might even agree on the "incredible" part, but I am afraid
we might disagree on the direction...]

Ok. Thanks ;-)
