Help/Documentation contains instances of "<emph/>", which are usually preceded by redundant spaces too. 
Yes, the slash is at the end of the element, which means it's probably an erroneous element.

Example strings from the Help @ Pootle:

When you insert an object, graphic, or frame, an anchor icon appears where the item is anchored. You can position an anchored item by dragging the item to another location. To change the anchoring options of an item, right-click the item, and then choose an option from the <item type=\"menuitem\">Anchor</item>         <emph/>submenu.

To insert the date as a field that does not update, click “Date (fixed)” in the <item type="menuitem">Select</item>               <emph/>list.

Please try to remove these tags, and clear redundant spaces.
