Trouble with opengl snappy interface

[Reinhard Pointner]

I've solved the fontconfig issues by including all fonts and fonts.conf in
the snap. My Java Swing app manages to start up at at least. There seem to
be a few opengl/gtk issues though.

`export LIBGL_DEBUG=verbose` is set.


(process:6285): Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.

(<unknown>:6285): GdkPixbuf-WARNING **: Cannot open pixbuf loader module
file '/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache': No

This likely means that your installation is broken.
Try running the command
  gdk-pixbuf-query-loaders >
/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache
to make things work again for the time being.


Another question regarding D-Bus interop:

"Desktop Actions" like Open/Browse/Edit don't seem to work in the snap. In
--devmode using dbus to talk with unity/gnome shell shouldn't be an issue,
correct?


Cheers,
Reinhard
