how do i parse a yaml set with perl

david2008 has asked for the wisdom of the Perl Monks concerning the following question:

Hi all, I get a yaml file like described here.
When i try to parse it with YAML::Load i get the following error.

YAML Error: Invalid element in map
   Code: YAML_LOAD_ERR_BAD_MAP_ELEMENT
   Line: 4
   Document: 1

Which library is capable of parsing this?
Thanks,
David
