Now it works.

No, your code is wrong. You messed up with the index to the copy of the key and value.

After lua_next() your stack looks:
 table key value *
The index of the key is -2, and the index of the value is -1.
After lua_pushvalue(L, -2) your stack looks:
 table key value copy_of_key *

You should work with the copy of the key. Its index is -1. Value's index is -2.

After lua_pop(L, 2) your stack looks:
 table key *
Got it?
