Taxonomy Metaboxes not translated (Post Edit page)

[bokamm]

Describe the bug The taxonomy metaboxes (for choosing categories and tags) on post edit pages stay English even if another language is selected. Without qtranslate-xt, these metaboxes appear in the language set in Settings > General. In the tags metabox, only the "Separate with commas or the Enter key." line is translated. This happens on a clean install as well as long-running websites.

To Reproduce Steps to reproduce the behavior:

1. Edit an existing post or select "Add New."
2. Check the metaboxes for the post attributes to the right.

Expected behavior Metaboxes for taxonomies should be translated (as are the metaboxes "Summary," "Featured image, "Excerpt" etc.

Screenshots English to the right, German (with and without translate active) to the left.
