Comment 4 for bug 668375

Ted's workaround does work on 11.04 Unity. Unfortunaley in previous versions of the Application Indicator custom icons can not rendered this way. However we need to make sure that applications can be run on all supported Ubuntu versions. Therefore an application that needs a custom icon (e.g. for displaying a program status) cannot use application indicators the way they are now.

As status icon is deprecated the only way would be to use windows default icon to display a program status. However an updated windows icon is no longer rendered in Unity (see bug #695060) too.

This matter desperately needs action because we do not want to include all icons of any application in our icon themes, and developers will not be able to develop a whole icon theme just for their single app to run.
