Jacek, do you have any thoughts?
Created attachment 125625 [details] patch Issue was that the Plug-in registry initialization job was trying to refresh view when it was actually closed. Patch solves this issue in few ways: 1. terminate job when view is closed 2. check that UI is not disposed in all public PluginRegistry methods, before UI calls. I have also removed completely unused or reduced visibility of internal PluginRegistry methods.
Patch is ready :-)
Thanks Jacek.
done. > 20090213
