This I know (else, never let me near a computer again!)...

...this I didn't. I'm using Qt for embedded software and there is no 
command line interface to the applications. They're started and left 
alone. I've never paid any attention to how QApplication uses the 
arguments. Good thing I've only ever instantiated it directly from main() 
or I'm sure I'd have made exactly the same mistake as the OP.

Not sure I like having the parameter list modified but that's just a 
personal preference and I can understand why it's done in this case.
