Hi,

please don't just paste logs like this: post them somewhere and provide a link, as otherwise this messes up the automatic issues references.

That said, I'll look into this ASAP.

I've not been able to replicate the issue, but if the issue is with the map of listeners, I've strenghtened its management using a lock to avoid potential race conditions. Can you let me know if that solves the issue for you?
