Source: New Layer import takes forever to error #526

I've noticed on some .shp files I've tried to import that I will try to submit the file and clicking the button doesn't seem to do anything. That's because it's made this request http://localhost:3000/metadata?file=/Users/camille/Downloads/ne_10m_graticules_all/ne_10m_graticules_30.shp and it's still pending and waiting. Eventually (a minute or two later) you see "(failed) net::ERR_EMPTY_RESPONSE" in the network tab and this:

This bug you found helped me find a callback error. Woot!
mapnik-omnivore is having trouble setting min/max zoom for these graticule sources. I'm looking into this now.

@camilleanne this issue should be fixed with my last tm2 update (fixed mapnik-omnivore).
