• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Tassilo Horn 2011-05-03 09:04:39 UTC]

When trying to start gnome-tweak-tool-3.0.3, I get this AssertionError:

 % gnome-tweak-tool 
INFO    : Caching gsettings: <gtweak.gsettings._GSettingsSchema: org.gnome.desktop.interface>
Traceback (most recent call last):

    **options)
  File "/usr/lib64/python2.7/site-packages/gtweak/widgets.py", line 140, in __init__
    assert len(key_options) > 0

After commenting out these 2 assertions, it seems to work fine.  Now I've commented the assertions and added 2 statements:

        print schema_name + ", " + key_name
        print key_options

The tweak tool starts (and works fine), and the output is that:

So it seems the key cursor-theme is missing in org.gnome.desktop.interface.

The installed theme/schema packages are:

x11-themes/gnome-themes-standard-3.0.1
gnome-base/gsettings-desktop-schemas-3.0.1

[Comment 2 Andreas Mielke 2011-05-03 10:09:04 UTC]

Please sync the Gnome Overlay und emerge gnome-tweak-tool-3.0.3-r1.

I already tried this approach, and it has problems. See the comments in the ebuild.
