Is this a bug in wings_export?

[nemyax]

From wings_export.erl:

Code:

export(Exporter, Name, Ps, #st{shapes=Shs}=St0) ->
    St = wings_view:freeze_mirror(St0),
    ...

Apparently this is supposed to freeze the mirror before continuing to work with the meshes. However, Shs is bound before the freeze.
Shouldn't it be like this instead?

Code:

export(Exporter, Name, Ps, St0) ->
    St = wings_view:freeze_mirror(St0),
    Shs = St#st.shapes,
    ...
