I heard this morning from one of the engineers who monitors the crash logs mention something about "weird things being done in apps that are causing the XDK to crash" -- which is probably referring to your app. That's not meant to blame your app, but only to point out that engineering is trying to understand what is causing this problem.
The only thing I can suggest, at this point, is to use the Debug tab or see if there's something about your code that is causing this to happen. If you do discover some aspect of your code that is causing this, please report it here, it will be easier for us to resolve the issue. If you are able to share an app that causes this, please ZIP the ENTIRE project directory (including all files therein) and send me a private message with a link to that app. I can forward it to engineering.
