stgit: No patches to pop

Hi,

I've just recently started using stgit (v0.11, git v1.4.3.4). On a
test repository, I do:

% stg applied
first
second
third

but when I pop I get:

% stg pop
stg pop: No patches to pop

I also get things like:

% stg pop second
popping patch "third"... done
Now at patch "second"

Is this normal?

Thanks,
