The nodes I tried to copy are in the screenshot.
Hit an ensure before the crash:
Ensure condition failed: ScriptVariable != nullptr [NiagaraScriptGraphViewModel.cpp] [Line: 294]
Script variable should already exist when we copy nodes referencing them!
Selected a few nodes, Ctrl-C to copy -> crash

There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-155442 in the post.
