Bug description:
[Impact]
Backport git patch that fixes memory corruption in libgweather that is
causing gnome-shell to crash. This is particularly bad on wayland as it causes
the user to lose their sessions
I believe this should also fix bug 1688208 and potentially a couple of
other high ranking crashes on errors.ubuntu.com. I have not however
found reliable reproducers for those other bugs.
[Test Case]
After update of libgweather
1. Ensure org.gnome.Weather.Application locations is not set (as per default
setting)
2. Disable Location Services
3. gnome-shell should not crash
[Regression Potential]
Low, the patch merely fixes a refcounting bug. Given the high impact of this
bug, this is an important fix.
