core20 - bug after pressing done after entering email address

[Paul Larson]

I was testing core20 on a rpi4 (1GB) with the armhf image from http://cdimage.ubuntu.com/ubuntu-core/20/beta/20200512.3/ and testing the reinstall option. After booting to do the reinstall, I got to the point where I had just entered my lp email address and pressed enter on the [done] button. Here was the traceback I got:

Traceback (most recent call last):
  File "/usr/bin/console-conf", line 11, in <module>

  File "/usr/lib/python3/dist-packages/urwid/wimp.py", line 648, in keypress
    return self._current_w

After that, I pressed enter and console-conf started over from the beginning, except this time it worked. This is the first time I've seen this, so it may be pretty hard to reproduce.

Here's a tarball with the contents of /var/log/console-conf in case that's helpful
