Ext3 users - May 2007 - 2.6.21: ext3 related crash

One of our squid proxies crashed today. I was able to make a
screenshot of it's last utterings - and since ext3 is being mentioned
there, I thought I'd mention it here:

This is dumping a core file into an ext3 filesystem, and because
the top of the stack is not visible there is no real indication
what the actual problem is.
