findAll not accepting Pattern as argument

1: Sikuli 0.9.8
2: OS X 10.5.8
3: Write a script that uses findAll with a pattern as the argument (as documented at http://sikuli.org/doc/pythondoc-python.edu.mit.csail.uid.Sikuli.html#python.edu.mit.csail.uid.Sikuli.findAll-function ), my simple test example is the following:
finders = findAll(Pattern( ).similar(.96))
the argument to Pattern here is an image of the OSX Finder icon from the dock)

TypeError: findAll(): 1st arg can't be coerced to String

if I change the "findAll" in my example to "clickAll", "click", or "find" it works, just fine.
