[fixed] Face|RMB Bridge crashes Wings

[Fonte Boa]

Marcin, did you use LMB Bridge or RMB Bridge? LMB Bridge works for me, RMB Bridge generate a wings_crash.dump...

Micheus, the command works fine if user select two faces in different objects.
If these two faces belong to the same object, the command crashes Wings.

It seems i am the only awarded with these stranges bugs... Not luck...
