I did try that but get the following error from crash:

crash: /var/xen/dump/2007-1025-1628.22-Wolf02Guest1.1.core: not a
supported file format

However, file seems to think it is the following:

file /var/xen/dump/2007-1025-1628.22-Wolf02Guest1.1.core
  /var/xen/dump/2007-1025-1628.22-Wolf02Guest1.1.core: 
  ELF 64-bit LSB core file Intel 80386, version 1

And the fact that gdb and gdb-server can get some information out of it
suggests that it's not a completely invalid dump.

Thanks

Kieran
