Bug#449351: sed: Fails to dist-upgrade: fails while processing post-installation script

Package: sed
Version: 4.1.5-4
Severity: important

*** Please type your report below this line ***

"aptitude dist-upgrade" fails with the message below. Judging from the
message, I doubt this is because I am using xen with amd64 environment.
