It will also break indicators support for lxpanel (LXDE panel) and Awn
(avant-window-navigator), which will not be ported to GTK3 during this

For Lubuntu, it's problematic, because we can't rely on the fallback
icons on the notification-area, when indicators-application is not
enable. We had several bugs during the last cycles, some are not yet
fixed (network-manager with 3G for example). That's why we are planning
to add indicator-application by default for quantal, on Lubuntu, on the

Micah told me about this drop (very briefly) at UDS, and the plan was to
upload a GTK2 version in universe, which sound acceptable.

As a side note, it's a bit unpleasant to first, have to implement a new
API, usefull only on Ubuntu and partialy on Debian, and now be forced to
migrate to GTK3 to still support the indicators. Removing GTK2 support
means removing approximately half of the providers of indicator support
