Comment 23 for bug 965953

I have been inserting debugging in formation and here is a trace that I am getting when I click on the Skype entry in the indicator applet. For some reason, whenever the items in a menu change, then all items of the menu are removed and then inserted again. For Skype this seems to happen every single time I open the menu. When I open other menu items such as bluetooth or Ubuntu One, then the entries are not removed and inserted. But the menu simply opens. However I can reproduce the same phenomen with network-manager. When I open the menu and then pull the network cable I can see how all items get removed and then re-inserted.

From the trace I can see there are 20 items removed from the Skype menu, but 21 added. This explains the 22px size difference between the first and last size_allocate call. I have not measured this, but it seems the menu is painted with a height of 356px while at the end it has 378px thus requiring scrolling.

Note that the menu is a member of 'IndicatorObjectEntry' (from libindicator) and indicator-applet has no control over adding or removing entries.
