undefined function taxonomy_get_vocabularies

Issue Summary

Hello,

I have run into a problem. I have a site where I am not using Taxonomy module. For some reason, Syndication module requires to check for taxonomy vocabularies while not checking whether the Taxonomy module is active. I am getting this error:

Fatal error: Call to undefined function taxonomy_get_vocabularies() in ... sites/all/modules/syndication/syndication.module on line 436

I am just assuming the above statements so if it is not precisely it, I apologize.
