SP4: Delete engine: please list pages in their existing language - no NULL please!

I have a site with two lang. My page and my sub page only exists in one lang only (and both are validated).

When trying to delete such a page from the other lang:

• the current page (whcih does not exist in the current lang) is displayed in the delete engine with the title from the other lang
• the sub-page warning indicates a null value

So could we rather indicate, more properly and consitently, the stauts of the page in the current lang (so no null . but "Page N/A" and the title in the other lang if present (so something like "Page N/A (FR: Page1 / De: Page1)")
