I20101208-1300 (3.7M4)

1. Install 'Eclipse XSL Developer Tools' from the Indigo site.
2. Restart when prompted.
3. Window > Open Perspective > Other... > XML
4. Activate the 'XPath' view.
5. Ctrl+F10 > Edit Namespace Prefixes
6. Nothing happens. An NPE is logged.

The code assumes that there is an active editor around (not always true). Perhaps the menu item should not be enabled if there isn't an active editor? Or maybe completely hidden?
