Got the bug. Actually, there are three bugs:

 + libgksu calls 
   sn_launcher_context_set_description (context->sn_context, _("Granting Rights"));
   However, it doesn't make sure the string is UTF-8.

 + libsn should not accept this string in sn_launcher_context_set_description().
   Also, in xmessage_func(), libsn should make sure the description (and all other elements) is UTF-8.

 + libwnck assumes that libsn gives valid UTF-8 strings.

Fred, Sebastien: can you report the libgksu bug? I can't open a bug there without creating an account, it seems.

I'll report the libsn bug, and commit a fix for libwnck.

Oh, I was wrong about libsn: there's no bug there. We just weren't telling it to use the glib utf-8 validator. Fixed now.
