(v2.2.8) Wings3D crashed when combine two objects that has differnt material.

[tkbd]

This time, I test only it in OSX,so I don't know it happend in Windows.
How to recreate the crash?
1) Create an object with Material A.
2) Create an object with Material B (+ UV).
3) Select both objects(A&B),and BODY>Combine
4) Wings3D app crash.
I got these logs.

For the time being,If you want avoid the crash,Apply same Material to the objects before combine.

tkbd, thanks for report it.

I tried your steps on Windows 10 and I have no problem.

Seems like something else crashes earlier and kills the window,
since the gui calls indicates that the gui is gone.
