Hi, for the records (and future searchers):
As per https://developer.apple.com/library/mac/qa/qa1773/_index.html (I should
have read this one before) the importer have to be signed with the same
identity and entitled for com.apple.security.app-sandbox.
To check if the importer works you *must* move it in the /Applications folder
(ie: executing the main app in the debugger is not enough).
The main issue is that under Mavericks embedded spotlight importers not signed
don’t work anymore (correctly, in a way).
