File corrupted on crash reboot. Can someone help diagnose?

[Pierre Abbat]

I had an email that I was writing to a few people. The computer rebooted 
itself. I restarted Kmail and found the message window empty. I cd'ed into the 
directory where it keeps autosaved copies of email being composed and found 
that it had been overwritten with zero bytes. Fortunately I could recover the 
content with undo (I've had this happen on Linux and was out of luck). Can 
someone receive the undo output and the reboot times and figure out what 
happened? I don't want to post it publicly, as it's a personal email, but I 
can send it privately to a developer.
