So rtpmidi process keeps running during the loop, that is, it's only
about connection and disconnection, right?
Also, you're listening to an event during that -- but how?

In general when you report a bug, more detailed description about the
test itself would be really helpful.  At best, provide a PoC, which
makes the debug much easier.  Posting only the stack trace without any
other information is, OTOH, almost pointless.  One can't decode the
address for a binary built for a different system easily, either.
