After idling, crash on sending data to websocket

[digitalcircuit]

I'm not yet sure of what causes this issue, but I'll try to update the description/add comments as more is discovered.

bitlbee-discord crashes in trying to send data to the websocket when setting presence to online whenever /away is removed from Bitlbee.

Possible steps to recreate:

1. Join Bitlbee in a client, set up Discord, join a few channels with periods of inactivity
2. Set /away
3. Wait a few hours, not sending anything
   • Some hours of no messages may be required
4. Remove /away, e.g. with /back
5. Crash

Actual situation that happens:

1. Connect to Bitlbee via Quassel core, join channels, etc
2. Connect to Quassel core with Quassel client
3. Chat for a while
4. Disconnect client from core, allowing automatic /away-on-detach to be set
5. Go do other things in life (usually happens overnight, so sleeping)
6. Connect client to core, removing automatic /away-on-detach
7. Bitlbee crashes immediately, restarting while client is attaching to core
8. bitlbee-discord prints several messages that were missed while reconnecting
9. Everything works, until step 4 again

Additional

Configuration

• Quassel IRC using latest master build
  • Enabled automatic /away on detach of client from core (think bouncer), /back (removing away) on reattaching client
• Bitlbee from the nightly PPA
• bitlbee-discord using commit b69685d.
  • Joined three servers, one has a 2-user channel joined, one has about ten 190-user channels, and the third doesn't have any channels joined
