I hope "bt full" is enough. It's attached to this mail and gotten using 
standard output redirection (anyone knows of a better way). This time, 
it took more than a day to crash Emacs (it didn't crash when I was 
wanting it to crash, but then crashed today when I had work to do, and 
clicked on the menu just to check if it's still stable ;-)).

I attach it uncompressed to ease viewing and because it's 10kb. How 
wants to limit the bandwidth, and is able to ignore attachments can find 
it on www.kvota.net/bugs in both compressed (gzipped) and uncompressed form.

Hope this helps!

Cheers,
Danilo
