Does this need to be a string16? You're converting it from a FilePath anyway.

[sky, 2013/08/30 17:06:56]

nit: when you wrap, one param per line.

Just to make sure I'm following you, you're saying I should pass it through as a
FilePath?  I didn't think FilePath's were IPC serializable, but I suppose I'm
probably wrong about that.

Done.

[zturner, 2013/08/30 18:10:06]

Done.
