I think ml2john.py (and agilekc2john.py too) should be chmod 755. On the other hand, when I did so and ran it (under OSX) using just ../run/ml2john.py, it failed: I had to use "python2.7 ../run/ml2john.py luser.plist". This works fine on native OSX.

For new formats it's always a good idea to verify how non-ascii characters are handled. In this case I presume it is UTF-8. Here is a test-vector:

$ml$37174$ef768765ba15907760b71789fe62436e3584dfadbbf1eb8bf98673b60ff4e12b$294d42f6e0c3a93d598340bfb256efd630b53f32173c2b0d278eafab3753c10ec57b7d66e0fa79be3b80b3693e515cdd06e9e9d26d665b830159dcae152ad156

Password is müller (muller but with an u-umlaut as second character). BTW I notice I got a higher iterations count than what you posted.

For source-code encoding safety, it should be declared like this in the format:

	{"$ml$37174$ef768765ba15907760b71789fe62436e3584dfadbbf1eb8bf98673b60ff4e12b$294d42f6e0c3a93d598340bfb256efd630b53f32173c2b0d278eafab3753c10ec57b7d66e0fa79be3b80b3693e515cdd06e9e9d26d665b830159dcae152ad156", "m\xC3\xBCller"},
