"This event can be used to trigger the creation of contents
or other tasks
that require the application to be fully operational : utilities
and indexes created in the catalog."
I understand utilities should be ready. In
fact, I have a print statement in the utility's __init__() which is
executed before getUtility() fails. I've also checked the
getUtility() call in the function is the same that is used in other
places and working just fine.
