Bug#920139: sddm: GTK and GNOME: Applications won't launch due error of glib2

[Bernhard Übelacker <bernhardu@mailbox.org>]

Hello Adrian,

> I don't have any of those old GNOME applications installed, you mentioned.

Then these files should not be there I guess like e.g.:
    /usr/share/glib-2.0/schemas/org.gnome.EasyTAG.gschema.xml

On a system where e.g. easytag is installed a 'dpkg -S' returns this:
$ dpkg -S /usr/share/glib-2.0/schemas/org.gnome.EasyTAG.gschema.xml
easytag: /usr/share/glib-2.0/schemas/org.gnome.EasyTAG.gschema.xml


However, if you suspect something of the environment may be wrong,
you could try this:

- login through sddm
    env | sort > /home/user/env-enlightment.txt

- login through another login manager
    env | sort > /home/user/env-other.txt

- compare:
    diff -Nurp /home/user/env-other.txt /home/user/env-enlightment.txt

- then you may search if GSETTINGS_SCHEMA_DIR in the differences shown.

- or set the different variables one by one in a terminal by
    export VAR=value
    (call from there one of the crashing programs)
  and check if that changes behaviour.

Kind regards,
Bernhard
