SUMMARY
Demonstrative video: https://www.youtube.com/watch?v=ujYLWQ2uelU
This is not possible to reliably reproduce. I had to go back and forth for
about 2 minutes in the demonstrative video to get it to repro and I haven't
been able to capture it on video ever since.
If you try to pair with an unreachable device, connect that device back to the
network and send a pair request back, you might cause the app to freeze. I
produced the coredump with SIGQUIT.
STEPS TO REPRODUCE
1. Connect a phone and a PC to the same network so that they see each other but
don't pair
2. Disconnect the phone from the wifi
3. Attempt to pair with the PC
4. Reconnect the phone to the wifi
5. Attempt to pair the phone
OBSERVED RESULT
The application might sometimes freeze unrecoverably
EXPECTED RESULT
No freeze should occur
