Excellent. So I guess the remaining question is: how did the header get 
corrupted in the first place.

I'll be sure to keep a closer eye on things next time I see this. I've 
seen this twice on two completely different systems (my home machine, and 
a production fileserver at work, both after upgrading to 1.6 [and I think 
they were both pre2]), so I'm sure I'll see it again, just a matter of 
time.
