Sometimes a separate frame gets automatically killed along with its
buffer, so you should not call `delete-frame' after `kill-this-buffer'.

However, in the special case there's another function which wants to do
something in the *Group* frame after you killed it.  You would have to
tell us which package is responsible for creating the *Group* frame in
order to find out where the error comes from.
