[pkg-wicd-maint] Bug#896600: wicd-curses: "AttributeError: 'Text' object has no attribute 'keypress'" in Preferences → Advance Settings → Backend when selecting "external"

[Axel Beckert]

Package: wicd-curses
Version: 1.7.4+tb2-6
Severity: normal
Tags: upstream

In wicd-curses, a crash can be provoked when going into preferences by
pressing "P", then choosing the tab "Advanced Settings", then selecting
the pull-down select box, pressing Enter to see the list of options, and
then choosing "external" (the default) and pressing Enter again to
accept that setting.

It seems irrelevant which setting was set beforehand.

Backtrace of the crash:

This bug report looks very similar to https://bugs.debian.org/814090,
but seems unrelated on a first glance.
