glyph_report.pl fails before building the table at the end

[Gartral]

glyph_report.pl is failing with an odd error when it should produce the table of available recipes, the exact error follows

YAML Error: Expected separator '---' Code: YAML_PARSE_ERR_NO_SEPARATOR Line: 1 Document: 2 at /home/gareth/perl5/perlbrew/perls/perl-5.14.2/lib/site_perl/5.14.2/YAML/Loader.pm line 81.

I've looked in both my login.yml and the yml file that's embedded into the scripts and I can see there's a separator in both. I'm stumped and posting here was a last-resort. Thank you kindly for your understanding.
