Also just noted this same assertion failure after a git merge on model. ?corrupt file - although Xcode 4.4 is able to read it.
Later: I think this related to fetch requests in the model: #114
Still later: Delete fetch requests -> generate model classes -> add fetch requests back as work-around

Looks to be a dup of #15
