wicd-curses crash when selecting and changing network configuration

[falcon]

After a fresh install from Arch repositories, wicd-curses crashes with "ValueError: None is not in list" when i'm trying to change a wireless network's configuration (with the right arrow key).

Here is traceback:
Traceback (most recent call last):
  File "/usr/share/wicd/curses/wicd-curses.py", line 1146, in call_update_ui

Dependencies (depth <= 1):

wicd 1.7.3-1
python2 2.7.9-1
python2-dbus 1.2.0-4
dhcpcd 6.7.1-1
wpa_supplicant 2.3-1

rfkill 0.5-1

Steps to reproduce:
1. pacman -S wicd
2. systemctl start wicd.service
3. wicd-curses
4. use the up/down arrow keys to select a wireless (!) network, and then use right arrow key to change its config

Actual results:
Immediately crash with python traceback (see above)

I've got this error only when trying to select a wireless network with arrow key, selecting a wired connection (with right arrow key) is fine (but the ESC key doesn't work correctly, i had to click it multiple times and then use left arrow key to return to network list).
