Bug#884391: gnome-control-center: Crash when adding Input Source in Region & Languages after enabling Show All Input Sources

[Andreas Sewe]

Package: gnome-control-center
Version: 1:3.22.2-3
Severity: normal

Dear Maintainer,

   * What led up to the situation?

I have an unusual keyboard (Apple aluminum British English), whose layout I
must unlock for GNOME using the Tweak Tool

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

- Open Tweak Tool
- Switch Keyboard and Mouse > Show All Input Sources to On
- In the Region & Languages settings panel, click '+' to add an Input Source

FWIW, two input sources were already configured: English (UK), German
(Macintosh, eliminate dead keys).

   * What was the outcome of this action?

This crash the settings application and leaves the following entry in GNOME
Logs:

  gnome-control-c[6902]: segfault at 945 ip 00007f3e8b443c50 sp
00007fffa4880298 error 4 in libglib-2.0.so.0.5000.3[7f3e8b40a000+112000]

   * What outcome did you expect instead?

A dialog opens that allows me to select my exact input source: English
(Macintosh, UK).

Indeed, the dialog opens with Show All Input Sources switches Off, but then
obviously my exact keyboard layout is missing.
