The problem is that ipython is itself a program that analyzes argv for
its own options, yet you want argv to 'pass through' to your own
program below.  For stuff like this I have around a little script I
call 'iprun' (I'm attaching it here) that runs programs with ipython's
machinery (exceptions, debugger) but otherwise leaves argv untouched.
You might find it handy.
