Export not working

@leo,

@yousef and I are trying to collect some stats about Discourse usage. One thing we’re trying to do is export a list of users with different trust levels, the export seems to work but then the file is 0 bytes. Can you help?

¯\_(ツ)_/¯

An update might fix the issue, I’m not sure. Otherwise, if we want to have more automagic stats, then everything should be available via the API.
