I signalled the first one in the translation page of the codex. One should avoid using apostrophes for the translation of image uploading related stuff.
Second bug (related): if an image has a name or description with an apostrophe in it, the pop-up menu will not show up. This is a serious bug since there is no way to change the name/description of an attachment after it has been uploaded.
The easiest workaround is to remove the line
include('edit-attachment-form.php'); (which is wrong anyway since this file doesn't exist) in
wp-admin/post.php and replace it by
include('edit-form-advanced.php'); and then remove the apostrophes in the name/description of the attachment by manually giving the
id of the attachment in the address:
http://yourblog.com/wp-admin/post.php?action=edit&post=85 (where 85 is the guessed number of the attachment).
Please report this as a bug; I don't know how to do that.
