siri crash

Question:

A very small number of users experience this crash:

NSInternalInconsistencyException:Use of the class INVocabulary requires the entitlement com.apple.developer.siri. 
Make sure you have enabled the Siri capability in your Xcode project.

But our project definitely has siri configured to be available.

During app startup, calling the following code causes a crash:

  INVocabulary *vocabulary = [INVocabulary sharedVocabulary];

Now that we can't figure it out, is it a bug in the system?
