For setting category name and description in many languages, you can use:
[[category:categoryName1]] and [[category:categoryDescription1]]
And then your categories will have a different name and description for every lang. That is OK.
Problem is with meta description on viewing category:
<meta name="description" content="&lsqb;&lsqb;category:categoryName1&rsqb;&rsqb;" />
