Comment 10 for bug 1023588

Xfce's indicator applet plugin, and the gtk2-based sound indicator and using the scroll wheel on the volume bar pops up two NotifyOSD notifications instead of one. I attached a screenshot.

Worth noting is that everything works as expected when clicking on the icon and changing the audio that way or using my notebook's audio controls - the problem only occurs when using the mouse wheel with the mouse on top of the icon, having not clicked it.

Uninstalling xfce4-volumed "fixes" this issue, but of course doesn't let me use my media keys on my notebook.
