CMDHELPER-2770 - Reported by Hekta

I got this stacktrace with this script, I was testing how different types of values are encoded in a yml.

chd_write('test.yml',
yml_encode(associative_array('a': 0, 'b': 1, 'c': -1, 'd': 0.5, 'e': -2.33, 'f': 'f', 'g': 'g g', 'h': array(), 'i': array(0, 1, 2), 'j': associative_array(), 'k': associative_array('a': 0, 'b': 1, 'c': 2), 'l': cslice(0, 10), 'm': closure(return(player())), 'n': closure(@t, return(@t)), 'o': null, 'p': '', 'q': true))
)

Please report this error to the developers, and be sure to include the version numbers: Server version: 1.6.2-R0.2-SNAPSHOT; CommandHelper version: 1628-32b6dcf. Here's the stacktrace:

Closures can't be serialized, as you see, but the stacktrace is still a bug. I have updated the docs and fixed the stacktrace, however.
