I've got the same kind of error.
Only get these error after a while when I connect with my phone that is connected to a VPN(without split tunneling) with other devices with VPN (with split tunneling) or without VPN I never get this error.
@archfan do you use a VPN by chance?

[aykevl]

I've had the same issue for a long time and finally managed to get a traceback, see this gist.

I don't use a VPN but I do have a flaky internet connection. I suspect the connection breaks at some point while being paused and the code doesn't know how to deal with it.

[matthijskooijman]

This might be related to #247, at least this comment contains pretty much the same backtrace. Might be different from the original reporter in that issue, though.

[raph2i]

Same thing here i think?
I can remember, that i connected my Android device at this time to an openvpn server

Looks like this is covered by #609
