Why are my UV coordinates distorted? When unwrapping a seamed object, my UV coordinates come out very weird. Whereas several sections have equal area on the model, they come out distorted when projected to the UV mappings:

I already tried applying the object's scale (Ctrl+A, Scale). It did help, but the UV is still distorted a bit. Is that normal, or am I doing something terribly wrong?

In Orthographic mode Numpad-5,  Back view Ctrl-Numpad-1.
You can unwrap it with U Unwrap from View without the distortion:
