You asked about the first problem people find when using PyQt or PyKDE.  I can't speak for
everyone, but this was the first thing I ran into.  Still, it was remarkably minor (the hair I
pulled out will grow back).  I just happened to be programming something unusual.  

Beyond searching through the posts in this newsgroup, do you think there would be a way to prevent
folks from making the same mistake in the future?  The error message was clear once I understood
that neither exec() or exec_loop() was a slot, but beforehand I was having trouble with that
