Client crashes when connection to remote times out

[peshence]

What happened?

Actual results:

Panic and crash

Expected result

Possibly a message that connection timed out and return control to calling function?

What are the steps to reproduce the bug?

Running a retreive request with pyfdb trying to connect to a remote FDB which e.g. is behind a firewall, so connections hang and eventually timeout.

Version

5.13.106

Platform (OS and architecture)

python:3.11-slim-bookworm
