line.rsplit(None, 1)

seems to do the trick for me:

 >>> tests=[
... 	("text (xxx)", ("text","(xxx)")),
... 	("text (text) (yyy)", ("text (text)","(yyy)")),
... 	("text (text) (text) (zzz)", ("text (text) (text)","(zzz)"))
... 	]
 >>> for test, result in tests:
...     r = test.rsplit(None,1)
...     if r[0] <> result[0] or r[1] <> result[1]:
...             print test, result
...

shows that the results of rsplit() match the expected results.
