(debian/testing on 32bit notebook)

I'm running xfce4-power-manager built from git master since switching my system to systemd (no updated version is yet in the debian repository). The daemon runs ok, but the settings dialogue crashes (SIGSEGV) after an apparently random time: sometimes before gui is up, sometimes after.

I tracked down the commit responsible to:
    http://git.xfce.org/xfce/xfce4-power-manager/commit/?id=47d4ba88c43f97427746839363bced83e191afc1

Reviewing the code there, I see an unwise (IMHO) use of strcat() which is evidently leading to memory corruption. Here's a rewrite of the last block of code in that commit, which fixes this for me:

        {
            gchar *str2;

            /* TRANSLATORS: Unit here is Watt hour*/
            str = xfpm_info_get_energy_property (energy_full, _("Wh"));
            str2 = g_strdup_printf ("%s (%d%%)", str, (guint) (energy_full / energy_full_design *100));

            update_device_info_value_for_name (view, list_store, _("Fully charged"), str2);

            g_free (str);
            g_free (str2);
        }
