Pkg xen devel - Nov 2010 - Bug#603391: pygrub: unintelligible error messages

Package: xen-utils-4.0
Version: 4.0.1-1
Severity: normal
File: pygrub


The pygrub awesome error messages are captured below.

Please tell me what pygrub was doing and why it failed.

I also don't understand why <image> is supposed to be an integer.
