Error with 0.11.5 (+ 0.11.4, 0.10.4) on Tumbleweed: No GSettings schemas are installed on the system

[fusion809]

Linux distribution and version

openSUSE Tumbleweed 20180427 snapshot.

Flatpak version

0.11.5, but error also occurred with 0.11.4 and 0.10.4

Description of the problem

Running:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo 

per instructions on Flatpak website returns:

(flatpak remote-add:7293): GLib-GIO-ERROR **: 21:35:08.461: No GSettings schemas are installed on the system
[1]    7293 trace trap (core dumped)  flatpak remote-add --if-not-exists flathub 

Steps to reproduce

Install openSUSE Tumbleweed, install Flatpak from official repos, or from my unofficial repo: https://build.opensuse.org/package/show/home:fusion809/flatpak, then run the above flatpak command.

It is quite frustrating and yes gsettings schemas ARE installed, I have even tried re-installed them with ZYpp using the command:

zypper in -f gsettings-desktop-schemas

but I still get this error. As I suspect it might be a simple matter of Flatpak expecting the schema files to be somewhere they're not here's what rpm -ql gsettings-desktop-schemas returns:

Never mind I found out that the issue was a fault XDG_DATA_DIRS variable, just had to add /usr/share/glib-2.0/schemas to it.

[matthiasclasen]

it should be enough to have /usr/share in XDG_DATA_DIRS, the code should know to check in the glib-2.0/schemas subdirectory.

it should be enough to have /usr/share in XDG_DATA_DIRS, the code should know to check in the glib-2.0/schemas subdirectory.

that fixed it for me (I was using WSL)
