WhisperBack freezes if trying to send while connected to LAN but not to Tor
From wb:2d15fc8a4e973b4c2d9c03d245d48ddf
Steps to reproduce:
- Start Tails
- Connect to LAN but not to Tor
- Start WhisperBack
- Click Send
- Click Close
- Click Send again
The whole GUI gets unavailable.
Looks a bit like #18552, but I couldn't even quit WhisperBack from the GNOME top navigation bar.
