Hi again,

A better backtrace:

Switching to Thread -1228847408 (LWP 4293)]

The line is:

g_return_val_if_fail (GTK_IS_SOURCE_LANGUAGE (language), NULL);

but i don't understand why... Are compatible gtksourceview 1 and
gtksourceview 2?

I paste my function, perhaps it help you:

static GList* gtc_snippets_provider_real_get_data
(GtkTextCompletionProvider* base, GtkTextView* completion, const gchar*
event_name, gpointer event_data)
{	
	GHashTable *snippets;
	GList *snippets_list;
	GtcSnippetsProvider *prov;
	gchar* lang_text = NULL;
	
	prov = GTC_SNIPPETS_PROVIDER(base);
	
	if (strcmp(event_name,USER_REQUEST_EVENT)==0)
	{
		g_list_free(prov->priv->active_list);
		prov->priv->active_list = NULL;
		prov->priv->temp_view = completion;
		
		if (GTK_IS_SOURCE_VIEW(completion))
		{
			//Es una lista y no un hashtable
			GtkSourceBuffer *buffer =
GTK_SOURCE_BUFFER(gtk_text_view_get_buffer(completion));
			g_assert(buffer!=NULL);
			GtkSourceLanguage* s_lang = gtk_source_buffer_get_language(buffer);
			
			if (s_lang != NULL){
				lang_text = gtk_source_language_get_name(s_lang);
			}
		}
		if (lang_text!=NULL)
		{
			snippets_list =
gtk_snippets_loader_get_snippets_by_language(prov->priv->loader,lang_text);
			if (snippets_list!=NULL)
			{
				g_list_foreach(snippets_list,gtcsp_list_for_each_add_snippet,prov);
			}
		}
		else
		{
			snippets = gtk_snippets_loader_get_snippets(prov->priv->loader);
			if (snippets!=NULL)
			{
				g_hash_table_foreach
(snippets,gtcsp_hash_for_each_add_snippet,prov);
			}
		}
		prov->priv->temp_view = NULL;
		return prov->priv->active_list;
	}
	
	return NULL;
}


S.O.S. !!!!!
