Fedora 30: FEDORA-2019-ac2a21ff07 Moderate: gnome-desktop3 SELinux Error

gnome-desktop contains the libgnome-desktop library as well as a data

file that exports the "GNOME" version to the Settings Details panel.

The libgnome-desktop library provides API shared by several applications

on the desktop, but that cannot live in the platform for various

reasons. There is no API or ABI guarantee, although we are doing our

best to provide stability. Documentation for the API is available with

gtk-doc.

This update fixes a [bug](https://github.com/mesonbuild/meson/issues/5268) in

the Meson build system which caused binaries and libraries to incorrectly be

marking as requiring an executable stack. This makes them more vulnerable to

security issues, and also can result in errors caused by SELinux denials. This

update also provides rebuilds of all the packages that were built with the buggy

Meson, excepting packages for updates were already pending (in those cases,

those updates have been edited instead). This includes gnome-initial-setup,

which was affected by this problem, resulting in a [release-blocking

bug](https://bugzilla.redhat.com/show_bug.cgi?id=1699099) that prevented it

running correctly with SELinux in enforcing mode.

[ 1 ] Bug #1699099 - gnome-initial-setup 3.32.0+ crashes due to SELinux denials (because it has execstack flag set, because meson 0.50.0 sets it when it shouldn't)
