[Bug 3912] Review request: lives - Video editor and VJ tool

OK, let's try to debug this. Please try these things in sequence: edit preferences.c, and find the line: store = lives_list_store_new(N_COLUMNS, LIVES_COL_TYPE_PIXBUF, LIVES_COL_TYPE_STRING, LIVES_COL_TYPE_UINT); replace this with (recompile and test each time): 1) store = gtk_list_store_new(N_COLUMNS, LIVES_COL_TYPE_PIXBUF, LIVES_COL_TYPE_STRING, LIVES_COL_TYPE_UINT); 2) store = gtk_list_store_new(3, GDK_TYPE_PIXBUF, G_TYPE_STRING, G_TYPE_UINT); 3) store = gtk_list_store_new(3, G_TYPE_INT, G_TYPE_INT, G_TYPE_INT);
