I'll try it tonight.

My report was based on linux-image-2.6.18-5-xen-amd64 2.6.18.dfsg.1-13etch4.

I will bootstrap a Lenny domU and run it with this kernel packages:

[http://ftp.debian.org/debian/pool/main/l/linux-2.6/]
linux-image-2.6.18-5-xen-amd64_2.6.18.dfsg.1-16_amd64.deb 
     04-Oct-2007 15:47   1.6M
linux-modules-2.6.18-5-xen-amd64_2.6.18.dfsg.1-16_amd64.deb 
     04-Oct-2007 15:47  14.6M

Then I'll make some mounts and install fuse-utils 2.7.0-2, then upgrade 
it to 2.7.0-3.

By the way... On the box where fuse crashed yesterday, I reinstalled the 
fuse-utils package. Unfortunately, I don't have the original output from 
dpkg anymore while it failed upgrading. But it will show up if I can 
reproduce it.
