params.append("%s=%s" % (param, repr(s.kwonlydefaults[param])))

, the value of s.kwonlydefaults can apparently be None in the case where there are keyword-only args, and none of those keyword-only args have defaults (e.g., def foo(arg1, *, arg2, arg3). This raises a TypeError, not a KeyError. Perhaps it is worth adding the TypeError to the except clause?
