Detlev,

Thank you for your continues effort.  I saw your email to pyside with 
the bug report, today I think (our time - Australia).  I think they  
did fix it.   As I use binaries, I will have to wait a while, or take a 
deep breath and face the compiling  :).

I wandered why all programs failed in the same manner, reporting 
incompatibility of argument in QApplication(argument)!

You have a great program, you do great work and show immense endurance 
-  congratulations and a well deserved THANK YOU.

OldAl.
