Comment 2 Tomas Pavek 2012-11-07 13:29:34 UTC 
The exception indicates some setup problem, there is no GuardedSectionManager. In the log I can see a strange exception java.lang.IllegalArgumentException: No parser for mime type: text/x-java.
Looks like if the installation was seriously broken.

I've made a fix that better handles the missing guarded support so it does not throw an exception.
