AttributeError: 'NoneType' object has no attribute 'send'

[splifter]

I've no idea how to provide more info than the message itself. This happens after 30sec after receiving a package. By the amount of messages flying through the cli, it seems this happens to each thread:

I'm having the same problem in a raspberrypi machine:

@splifter You can try an ugly workaround to always re-run the download automatically when the exception happens (to me this problem doesn't happen every 30s, it's random, so in my case it's worth it):

while [ "$ok" != true ]; do xdcc-dl "XDCC-DL-COMMAND" 2>&1 | tee /tmp/xdcc-dl.log; \
if ! grep -q AttributeError /tmp/xdcc-dl.log; then ok=true; fi; done

This calls the command again until AttributeError is not found anymore in the logs.
