1. Use GPG to generate revocation cert (Test.asc)
2. Double-click on Test.asc in Nautilus

Seahorse reports a spurious error (reported elsewhere), but still
revokes the key. I think it should notify the user that they're not
importing a normal key. Revocation is a pain to manually undo (from what
I've seen), and Seahorse does nothing to indicate that the file is about
to have an effect on existing keys. Obviously if you've just generated
it you should know what it does, BUT

- The user might not expect seahorse to run as the default action (I
used to have leafpad set to open .ASC files, forgot I hadn't changed
that...)

- The user might just find the revocation long after generating it,
forgets what it is, tries to import it..

PS. This hasn't bitten me yet, I noticed it on a test key thankfully;)
