libxl: xl crashes

[Christoph Egger <Christoph.Egger@amd.com>]

Hi,

xl crashes very early.
To repeat just run 'xl list' or 'xl create'

(Yes, 'xl create' w/o specifying a config file)


The line where the crash happens was last modified in changeset 
21000:3138b3885999.

Core was generated by `xl'.
Program terminated with signal 11, Segmentation fault.

Reverting the changesets 22733:0b04aea87667, 22734:1434b8515233 and 
22735:cb94dbe20f97  brings xl back to function.
