[platform-ui-dev] Remove action set from workbench

[Simon Schäfer <mail@xxxxxxxxxxxxxxxxxxx>]

This is a follow-up to my previous topic: http://dev.eclipse.org/mhonarc/lists/platform-ui-dev/msg05597.html

I have removed an action set from my plugin.xml. Now, each time Eclipse starts I get the error message

Unable to associate action set with part: xxx.xxx. Action set yyy.yyy not found.

I tried to remove the action set as described in this article http://random-eclipse-tips.blogspot.de/2009/02/eclipse-rcp-removing-unwanted_02.html but the action set seems already be removed (it is not found anymore), but at least it has an entry in

.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi

I wonder if it is possible to remove this entry (and some actions that were placed in the action set) automatically?
