[Qt-creator] Exited with code -1073741819.

I have fixed the problem with the extra libraries, but now I have a different 
problem, with qmake.  Many of the examples fail in the qmake step, like this:

Running build steps for project draggableicons...
Starting: d:/qt/2010.02.1/qt/bin/qmake.exe 
D:/Qt/2010.02.1/qt/examples/draganddrop/draggableicons/draggableicons.pro -spec 
win32-g++ -r
Exited with code -1073741819.
Error while building project draggableicons
When executing build step 'QMake'

The error code is always the same.  After such a failure the make clean always 
fails:

I haven't quite been able to identify what it is about the projects that fail to 
build.  I have ascertained that it is a mistake to Run qmake before doing Build 
project - this inevitably gives error -1073741819.  Once this error has occurred 
with a project, there doesn't seem to be any way to clean it up and start again. 
  That is, deleting files back to the original setup still doesn't allow the 
project to be built.  This is quite frustrating.  I'd be grateful for an 
explanation for what's happening here.  I am using Windows XP.
