Are you sure that it ask for the passphrase of the primary key?  It
should ask for the one of the subkey.  In any case, please enter the
passphrase of the subkey (which is usually the same as of the primary
key).  Note, that I have a very similar setup and it worked without
problems.  It is however possible that we have a regression here.

Yes, very easy:

 gpg2 --with-keygrip -K

shows you the keygrip of the keys.  Now, simply remove the file
