It looks like something very similar to an issue we had before Tabris 1.0 which was resolved by setting the 'Valid Architectures' in the XCode project to 'armv7' only i.e. remove 'armv7s' from the list.
I cannot remember the reasoning, but it was something we found with a Google search, tried it, and it resolved our issue.
We now have a different iOS issue with Tabris 1.0, but that will be another thread.
