Bug 34160

while emptying the garbage.

I just install Trunk version of Jahia.
I connect as lenya/levi
I go to the Admin slot
I click on 'Vider la corbeille' (i am in french so : empty the garbage)
And i get : org.apache.lenya.cms.task.ExecutionException: 
java.lang.RuntimeException: java.lang.NullPointerException
