The bug was related to trying to split a string with unstript spaces in
the action parameter. It resulted in a unbound error as there was no
previous raise when getting the key from args_funcs. The fix is twofold,
it makes sure that we raise the keyerror if we're trying to grab a non
existing key and we're stripping the spaces from the action before
splitting.
This should fix both the unbound error and the not being able to resolve
correct actions.
