Description Javier Hernández 2011-01-21 15:19:55 UTC 
I'm doing like this:

from gi.repository.Gio import Settings as GSettings
g_settings = GSettings()

... and I get a wonderful 'Segmentation Fault'

but, if i do like this:

g_settings = GSettings(scheme = 'yeah!')

No problem and i can work with g_settings scheme like a charm!

Regards!

Relevant traceback which explains why this is filed in glib/gsettings and not in pygobject/introspection:

In C-speak:

   g_object_new(G_TYPE_SETTINGS, NULL);

Should be enough to create the crash, while

   g_object_new(G_TYPE_SETTINGS, "scheme", "foobar", NULL);

Should be enough to avoid it.

Well, yes, gsettings with NULL schemas don't work. I guess adding a 

if (settings->priv->schema_name == NULL)
  g_error (...)

before g_settings_schema_new() would make it clearer that it's a programmer's error.
