Renaming a Link-Category Resets Link Widget Options of that Category

[hakre]

When renaming the name of a Link Category that is used as well in a Link Widget, the Link Widget stops working.

Step to Reproduce:

1. Create a Link Category "Test Start".
2. Add 10 Links into the Category "Test Start".
3. Go to the Widgets Screen and add a new Link Widget to a sidebar.
4. Select that Link-Widget and set it from "All-Links" to the Category "Test Start".
5. Visit your Frontpage so proof that the Widget displays.
6. Go to the Link Cagegory Editor and quick-edit the "Test Start" Category.
7. Rename it to "Test End".
8. Save Changes.
9. Visit your Frontpage.

=>> The Widget has disappeared.

Expected behavior: Widget displaying with the (renamed) link category.

Can't reproduce on 3.1-RC1-17157. The widget stores only the category ID and uses wp_list_bookmarks() for display. Changing category name or slug doesn't seem to have any effect.

We haven't fidgeted with Links since 3.5. This works for me now.
