Comment 128 for bug 439448

To continue my Comment #123, the French user reports (here: http://forum.ubuntu-fr.org/viewtopic.php?pid=3520937) that :
- Gnome has problem with its panel and its notification zone (indicator-applet) when the icons inside indicator-applet have to change their aspect (often network and battery).
-As soon as there is a change with the icons inside the indicator-applet, the bug happens at next boot.
- Unactivate wifi allowed him to solve the bug. But when he changed to wire network, the icon changes again, and the bug comes back.
- he thinks that the bug generally disappears when you extend the notification zone, and/or increase the width (>24 pixels) of the panel (he tested ~20 boots in different modes: connected, disconnected, battery, ...). The only problem of this workaround is that icons are not placed regularly...
- he thinks there is a random factor due to compiz (sometimes "Close/Maximize.>" buttons and shadow effects disappear)
