You don't have the issuer's certificate and dirmngr was not able to
retrieve it.  We fixed a lot of things in the last months, thus an
upgrade to the new backend is advisable - you may keep the old KMail
along with the cryptplugin and gpg 0.3.16.

Deleting the key is a mere

  gpgsm --delete-key USERID

if you also want to delete the private key, you need to do this prior:

  gpgsm -k --with-key-data USERID

Then look for a line like

grp:::::::::42EA1A8F1061AE86C6B2F4BE42704FA953EF0777:

and do

 rm  ~/.gnupg/private-keys-v1.d/42EA1A8F1061AE86C6B2F4BE42704FA953EF0777.key

Note, that in future versions the same private key may be used for
several certificates or OpenPGP keys; thus it is in general not
advisable to delete the private key if you don't know how it is used.
This is also the reason why there is no --delete-secret-key command
for gpgsm.
