Public bug reported:
Two of the appindicators I have written refresh themselves periodically
and on each refresh, rebuild their menu (and submenus).
I have noticed over time that the submenus disappear - the submenus look
as if each is a single space. The indicator itself, including the menu
items, is no longer responsive and the underlying process must be
killed. Memory does not seem to be increasing beyond what would seem to
be normal levels for a small script. Running the indicator from a
terminal reveals no error message.
I have attached a sample script which creates an indicator and a mock
menu/submenu. The update rate is every three (3) seconds: after a
couple of minutes, the submenu will change to the "space" version.
The script attached must be run using Python3.
The issue appears on Ubuntu 12.04/12.10/13.04 and Lubuntu 12.10 but NOT
Lubuntu 12.04.
I have written other indicators which use a single menu (no submenus)
and these indicators also periodically refresh (and rebuild their menu).
At this time, I've not noticed if these indicators become unresponsive
so I'm not sure if this is related to the submenus or if that is a red
herring.
