Proposed patch

Hi again,

An user reported that on 0.3.1, any text output by an indicator on the plugin isn't refreshed.

The following patch should fix it (ported to apply cleanly against master). The original patch is courtesy Jason Conti.

Someone also wrote a simple test case for that, if you're interested, it's available at <https://bugs.launchpad.net/ubuntu/+source/xfce4-indicator-plugin/+bug/877455>.

Thanks.
