GLib-GIO-ERROR **: Settings schema 'org.gnome.gcalctool' is not installed

I had a very similar problem with evince yesterday. I don't think that gcalctool or evince have the bugs in them, there's definitely a missing/corrupt library or something similar.

helkaluin@Eve:~$ gcalctool

GLib-GIO-ERROR **: Settings schema 'org.gnome.gcalctool' is not installed

Indeed, the error feedback is almost the same as with Evince. Seems like related to: https://bugs.launchpad.net/ubuntu/+source/glib2.0/+bug/602175

[Lars Kumbier (derlars)]

okay, the problem is based in not having Empathy installed, as there is a dependency in /usr/share/glib-2.0/schemas/ubuntu-artwork.gschema.override. This prevents the schemas from being built correctly, if Empathy is not installed (like on my system):

root@host:~# glib-compile-schemas /usr/share/glib-2.0/schemas/
No such schema `org.gnome.Empathy.conversation' specified in override file `/usr/share/glib-2.0/schemas/ubuntu-artwork.gschema.override'

Installing Empathy again or deleting the ubuntu-artwork.gschema.override, gcalctool works normally. As does Evince, which as the same problems: https://bugs.launchpad.net/ubuntu/+source/evince/+bug/621507

This seems directly related to this bug: https://bugs.launchpad.net/ubuntu/+source/glib2.0/+bug/602175

forgot: gcalctool works fine after installing Empathy again and recompiling the schemas, as given in the example.

[john mall (mantikor)]

It's not only gcalctool which works again. On my machine evince is running again too.

Thanks for the hint Lars.

Is there a possibility to install the libaries only instead of installing the whole bunch of stuff?
Here it was:

user@machine:~$ sudo aptitude install empathy
[sudo] password for user:

Do you want to continue? [Y/n/?]

Greetings John

[Jonathan Yip (helkaluin)]

And, gsettings-data-convert now runs fine.

Thank you, Lars.

[Lars Kumbier (derlars)]

@John: I'm not sure which package will install the correct schema. If you don't use Empathy, simple move the /usr/share/glib-2.0/schemas/ubuntu-artwork.gschema.override file to some backup and you should be fine after recompiling the schemas. Worked for me, and the file's contents indicate only stuff dealing with Empathy anyways.
