[4.7.2] Crash when assigning style to a Button

Hello,

I’m having a crash when I’m trying to set a button style to a button.
My Blueprint is quite simple :

If I’m not using the function and directly give the argument, the result is fine.

Here is the call stack I get :
E4Editor_SlateCore!UScriptStruct::TCppStructOps::Destruct() + 8 bytes [d:\buildfarm\buildmachine_++depot+ue4-releases+4.7\engine\source\runtime\coreuobject\public\uobject\class.h:868]

Any idea to avoid that crash ?
