"corrupted double-linked list" when running poller-wrapper.py

When running poller-wrapper.py, after LibreNMS has finished polling all devices, the Python script errors out with corrupted double-linked list as can be seen below. Before I start spending valuable time on debugging this, I am wondering if someone else has seen the same behaviour, and if someone perhaps knows about a solution.
