Can't go to edit mode on simplified curve

After simplifying curve if i go to edit mode that curve goes flat, made image to explain that better.

Checked in 2.71, 2.70, 2.69 same behaviour.

There is no example blend file attached or even a link to one (use and for some reason you decided to crop your screenshot so you’ve removed other useful info.

Supply a blend file so you make it easier for someone to help you

Your curve is a 2D curve. You would need to select 3D

Thank You!
