Python – collectd won’t recognize the python plugin

I am trying to load a super simple plugin I found online as a starting point, and collectd doesn't seem to recognize my python plugin. My conf file has the appropriate lines:

<LoadPlugin python>
    Globals true
</LoadPlugin>

...

<Plugin python>
    ModulePath "/usr/lib/collectd"
    Import "test"

    <module "test">
        test "input"
    </module>

</Plugin>

And my test.py looks like this:

import collectd

def configer(confObj):
    collectd.info('config called')

def init_fun():
    collectd.info('my py module init called')

def reader(input_data=None):
    collectd.info('my py read called')

def writer(input_data=None)
    collectd.info('my py write called')


collectd.register_config(configer)
collectd.register_init(init_fun)
collectd.register_read(reader)
collectd.register_write(writer)

I tried a lot of things including reordering the registers and some other things but no matter what my syslog spits out:

Jul 14 21:10:34 vagrant-ubuntu-trusty-64 collectd[21449]: python plugin: Found a configuration for the "test" plugin, but the plugin isn't loaded or didn't register a configuration callback.
Jul 14 21:10:34 vagrant-ubuntu-trusty-64 collectd[21454]: python plugin: Found a configuration for the "test" plugin, but the plugin isn't loaded or didn't register a configuration callback.

I've been pounding my head for hours and feel totally lost, any help appreciated.
