-- Information about the crash:
-- Information about the crash:
I believe my system and the hardware is automaticly included in this report. So I won't get into any details. It's just a dual core 2.2Ghz with 3GB RAM@667hz

- What I was doing when the application crashed: I was just changing from one activity to another. I have totaly four running in my system simultaneously .

That's it! 
Thanks and good luck.

The crash can be reproduced sometimes.
