Nike+ App Crashing?

I believe it is an Apple software issue. I've replaced my 7th gen iPod and the issue followed. I replaced the shoe sensor and I could not calibrate the new sensor. It continued to reset the iPod every time I got to 1/4 mile in the calibration process. I continue to have random resets. I have started setting my run distance further than I will actually run (as it seemed to crash at the end of the run). This seems to have helped a little. Very frustrating.

I have the issue, too, with two 7th gen nano's. I get the crash right after a spoken feedback milestone (usually near the end of the run). I've turned off spoken feedback and will test on my next run in a few days.
