[Fixed] Vertex|Connect shortcut (C) in UV Window crashes Wings

[Fonte Boa]

The issue is easy to reproduce.
Create a Cube.
Select one face.
Call RMB|UV Mapping.
In UV Map window, select that face, RMB click, Continue|Unfolding.
Select a pair of edges, hit "3" to divide them in 3 parts.
At this point, user is in Vertex mode (observing the workarea), but in UV Map window Wings seems to remain in Edge mode. It should change to Vertex mode...

Then, click "C" (Vertex | Connect shortcut) and Wings will crash!!!

Simplifying the description.

If, in this order, in UV Map window, user select two edges, divide them by hitting a number and then hit "C" (Connect), Wings crahses.

Just this.
