    upgradeProcess = addArgument("upgrade")

...has the effect of rebinding the name "upgradeProcess" to the object 
returned by the (non-existant) function addArgument(). The object previously 
bound to "upgradeProcess" is garbage collected (assuming it has no other 
names bound to it). I think you mean...

    upgradeProcess.addArgument("upgrade")
