I have noticed the new feature in the developer portal to allow us to view "crash logs" for live apps. I have a few comments about this.
First I am seeing crashes in the logs for my app that did not come from my app. The files that the crash is occurring in does not exist in my app and the listed app version doesn't exist for my app for several of the listed crashes.
Secondly while this feature is greatly appreciated it would be much more useful if we had a little more information. Ideally I would like to had a stack trace, variable values, and the actual error that caused the crash. Im not sure if this is possible as well but the serial number of the device that the crash occurred on would be very helpful to match it up with user bug reports.
