I've being checking this and it seems we'have a bug there. We'll try to 
solve it ASAP.

I've no explanation right now.  Maybe in the way the view works. Perhaps 
you've loaded layers on UTM or show, moved around, and when you've 
loaded this layer it trys to show in that way.

Opening a new view, and adding this WCS as the first layer must work as 
expected.

Thanks for your feedback
