Confirmed, for me this already hangs in node_clipboard_copy_exec
(probably endless loop because new node is automatically selected....)

assume this is caused by rBc6e3a20ab60b, checking...

This comment here (from rBc6e3a20ab60b):

this node is virtual, detached from any actual Blender data currently.

is actually not true in its current state (node is added to the nodetree).
Just pass NULL to BKE_node_copy_ex should do it: D4360
