dba_insert/replace/delete on an LMDB handler started a write txn into LMDB_IT(txn) while dba_firstkey's cursor was still bound to the read txn in that slot, so the next dba_nextkey renewed a freed handle. Close the cursor and abort the read txn before starting the write txn, and bail out of dba_nextkey when no cursor is open.
