Bug ID: 179171
Summary: [WPE][JHbuild] Gstreamer plugins that link with pango
outside of the JHBild
Product: WebKit
Version: WebKit Local Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: WebKit WPE
Assignee: webkit-unassigned at lists.webkit.org

Starting the WPE minibrowser (dyz) from a clean build (of the JHBuild) I see this warnings
$ WAYLAND_DISPLAY=wayland-0 Tools/Scripts/run-minibrowser --wpe
Starting dyz
xkbcommon: ERROR: couldn't find a Compose file for locale "C"
GLib-GIO-Message: Using the 'memory' GSettings backend. Your settings will not be saved or shared with other applications.

The warnings won't appear on the second run, as GStreamer will blacklist this modules on the local registry after detecting this and won't try again to load them.
That's because we are not building pPngo on the JHBuild and its picking the system-wide one, causing this problem.
A very similar issue was reported on bug 178918.
