Comment (by nacin):

 > I hit this on a recent project when we noticed multiple values were
 being stored on the same meta key without overwriting. We used the exact
 suggestion @nacin made above about deleting the key first then re-writing
 the value and it works fine.

 Deleting the key and then re-adding is only if you wanted to take the same
 row in the metadata table and change the ''key''.

 If all you want to do is update an existing key, then you need to pass the
 meta ID. This is the unique identifier for metadata in the XML-RPC API and
 is very important to ensuring that deletes, adds, and updates all happen
 properly.
