This is a minor bug.

I have a single GPG key pair (0xDD6D12BD), with multiple email address UIDs; they are ((©) = @):

- Remi.Denis-Courmont (©) via.ecp.fr
- rdenis (©) simphalempin.com
- remi.denis-courmont (©) centrale-paris.net
- courmisch (©) via.ecp.fr
- rem (©) videolan.org

Within Kmail, I also have several identities, all set to use one and the same GPG key pair for signing; they are:

- Remi.Denis-Courmont (©) via.ecp.fr
- rdenis (©) simphalempin.com
- remi.denis-courmont (©) student.ecp.fr
- courmisch (©) via.ecp.fr
- rem (©) videolan.org

When I tell Kmail to use  my key with an identity whose email address is not included in the key pair addresses (in this case, remi.denis-courmont(©)student.ecp.fr), it prints a warning, which is OK. That warning says that other users might have trouble with signed/encrypted email when the sender email does not match the signing key.

Then, when I configure an identity whose email address is one of my key pair UIDs, it does not print said warning, if the email address specified is one of:

- rdenis (©) simphalempin.com
- courmisch (©) via.ecp.fr
- rem (©) videolan.org

But it strangely prints a warning when the email address is Remi.Denis-Courmont (©) via.ecp.fr, which is obviously wrong. I'd suspect a problem with uppercase, though I use exactly the same case in GnuPG and Kmail.

Sincerely,
