That was presumably fixed in crash-5.0.6 by this change:

http://people.redhat.com/anderson/crash.changelog.html#5_0_6

 5.0.6 - Also available in Fedora Rawhide devel branch:
          build: dist-f14 crash-5.0.6-2.fc14
           http://koji.fedoraproject.org/koji/buildinfo?buildID=184746

       - Fix for support of xendump and Xen kdump dumpfiles from 2.6.27 and
         and later x86_64 kernels.  Without the patch, the crash session 
         would fail during initialization with the error message "crash: 
         cannot resolve end_pfn". 
         (ptesarik at suse.cz)

Although it is surprising (according to the changelog comment above) that
you are able to run with crash-5.0.1 and a xen kdump?

In any case, it's always beneficial to test with the latest upstream version
of the crash utility.  Your crash-5.0.1 version is more than 2 years old,
(ancient by crash standards), and so there's little chance of anybody
wanting to debug such an old version.
