Conversations hard crash (device shut off) lost data
 

Just had an interesting crash this morning. I sent an SMS (or viewed one I forget). I then closed the SMS window, then hit the X for Conversations to close it out. A minute or so later I opened up my N900 to use it and the screen wouldn't come on, it had shut off.

Flash forward to the next time I go to send an SMS. I open up Conversations only to find that it was empty! Luckily its not a big deal for me, but its still lame.

Are there any logs kept by the system that might shed some light on what happened?
