app runs fine in simulator but fails on iPad

My app has been running fine in the simulator environment but tried running for the first time on an iPad. It loads the first screen (which is a table view) but if I try to do anything, including just scrolling the table, it crashes. The Xcode organiser shows the following:

>

If I look in the crash logs in organiser all I can see is one from Safari dated weeks ago. How do I find the log referred to in the message above?

The app (TKD) is 16MB and the iPad reports 26GB available, so although there appears to be a reference to LowMemory, surely that isn't actually the problem? Am I doing something which is impacting FaceTime and why is there a message about com.apple.mobilephone on an iPad? Am I doing something horribly wrong?

Any help much appreciated!
