xfce4-indicator-plugin fails to restart the sound indicator

[GridCube]

Steps to reproduce:
Remove Plugin Indicator from the panel.
done.

it restarts only for the networking indicator, not the mailing or the sound.

this has been happening since 11.10

WORKAROUND:
add a new plugin indicator element to the panel, it replaces the broken one and all the indicators are back where they belong.

Hi,

Thanks for your bug report.

I think what you're experiencing isn't related to xfce4-indicator-plugin: when you remove it from the panel, there's no "indicator renderer" running anymore, and programs that support both indicator and systray (= "notification area") can detect that, and show an icon in the systray.
Network-manager-applet does that, but indicator-messages and indicator-sound are "pure" indicators and don't fallback to the systray, so they disappear, until you add back xfce4-indicator-plugin to the panel...
