[errors.ubuntu.com bug bridge]

Impact
======
GNOME Tweaks 3.30.2 is a new bugfix release in the stable 3.30 series. The only pratical change besides translation updates is a fix for running GNOME Tweaks in other desktop environments (such as Budgie or GNOME Flashback) than GNOME Shell. Before this fix, GNOME Tweaks would crash when run in those environments. This was a regression compared to 3.28 in Ubuntu 18.04 LTS.

Test Case
==========
From Ubuntu Budgie 18.10, install the proposed version of GNOME Tweaks.
Run GNOME Tweaks. It should start and run normally.

Regression Potential
====================
This update qualifies for the GNOME Stable Release micro-exception.

From a Ubuntu Budgie 18.10 live ISO, I installed gnome-tweaks 3.30.2-0ubuntu1 and verified that GNOME Tweaks now runs successfully.

[Johny Bens (johnybens)]

Installed gnome-tweaks_3.30.2-0ubuntu1_all via cosmic-proposed on full install of Ubuntu Budgie 18.10.
GNOME Tweaks almost ran successfully.

While changing setting (Both Shift together enable Caps Lock) in Keyboard / Additional Layout Options / Miscellaneous Compatibility options I got a segfault.

Interestingly the setting was enabled after restarting Tweaks and disabling and re-enabling the same (or other) setting did not repeat the segfault.
Whoopsie report send.
