HTTP Crawl errors involving &id;_lang= variables. Detail: 'domain not found'

[mowax]

In google webmaster tools, I have 21 HTTP errors. They are all product pages with variables of &id;_lang=. Next to each error it says 'Domain not found'. Here is an example:

http://www.dura-tex.co.uk/19-cable-mat.html&id_lang=1

I have only the english language pack installed. I don't know what makes this a crawl error, or how to get rid of these annoying variables. Can anyone help me?

I am having a similar problem. In my case, I have activated friendly URL
