[MapProxy] Reprojecting tiles and get_affected_bbox_and_level - raise NoTiles() error

[Martin Kokeš]

Hello list,

Could you guys tak look at this yaml http://pastebin.com/V6byruzB ? Basically I'm trying to shift resolutions and convert origin from northwest, levels limited global mercator grid to a standard global mercator grid as described in http://mapproxy.org/docs/latest/configuration_examples.html#reprojecting-tiles , but I'm getting:

Source inbound cache works fine, as you can see in case you replace zm layer source from [zm_cache] to [zm_cache_in].

Thanks for your attention
