From 8ac534fc002356b93e2015a8866f1ea89e3895f9 Mon Sep 17 00:00:00 2001 From: fujiwarat Date: Sat, 15 Dec 2012 17:40:18 +0900 Subject: [PATCH] Use Variant.unpack() instead of Variant.dup_strv(). Variant.dup_strv() returns a tuple in pygobject 3.2, e.g. (['space'], 1L), and a list in pygobject 3.4, e.g. ['space'] .
