[DRE-maint] Bug#596351: ohai fails with: to_json: source sequence is illegal/malformed

[Christopher Huhn, GSI]

Package: ohai
Version: 0.5.6-1
Severity: grave
Justification: renders package unusable

Simply running ohai fails on my box with the following error:

/usr/lib/ruby/1.8/json/common.rb:232:in `to_json': source sequence is illegal/malformed (JSON::GeneratorError)
        from /usr/lib/ruby/1.8/json/common.rb:232:in `pretty_generate'
        from /usr/lib/ruby/1.8/ohai/system.rb:222:in `json_pretty_print'
        from /usr/lib/ruby/1.8/ohai/application.rb:104:in `run_application'
        from /usr/lib/ruby/1.8/ohai/application.rb:75:in `run'
        from /usr/bin/ohai:47

A quick search on Google gives the hint that libjson-ruby might be too old.

Regards,
	Christopher
