Bug 284066 – kmail: not decrypting gpg-encrypted mails with passphrase with pinentry < 0.7.6

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Daniel Pinto dos Santos 2009-09-08 00:33:07 UTC]

When trying to decrypt a gpg-encrypted email with your private (passphrase-protected) key, kmail does not ask for a passphrase but complains it is wrong.
This can be fixed by installing >=app-crypt/pinentry-0.7.6 with USE="qt4".

Probably this should be added to the kmail ebuild.

Reproducible: Always

Steps to Reproduce:
1. Install kmail and <app-crypt/pinentry-0.7.6, have a passphrase-protected gpg-key.
2. Let somebody send you and encrypted mail.
3. Try to decrypt it.

Actual Results:  
Decryption fails. Passphrase was not asked for.

Expected Results:  
Decrypting should work after asking for the passphrase.

Oh it decripts.
You just have to specify your gpg agent.

scarab@Ugly-Elf: ~ $ cat .gnupg/gpg-agent.conf
pinentry-program /usr/bin/pinentry-qt
no-grab
default-cache-ttl 1800

This for example shows i am using for passwords qt3 version of pinentry dialog.

Feel free to reopen if you will be still unable to make it work.

(In reply to comment #1)
Well, I guess I should have said I was talking about kmail for kde4.
And if you want to use pinentry with that, I guess using a qt4 version is nicer.
Of course one could install a qt3 version which would require an installation of the whole qt3-stuff.
But even than, kmail should at least check for pinentry build with any qt USE-flag.
Because I just tested downgrading again, and as I have disabled the "qt3" USE-flag the same error occured.

ls /usr/bin/pinentry*                                                                                                                               
/usr/bin/pinentry  /usr/bin/pinentry-curses

That is not issue for kmail only.

It is dependant on pinentry/gnupg.

So if you set it correctly it works, otherwise you have problems.
You can use ncurses pinentry dialog, if you launch your kmail from konsole :]
But i would recomend you to use the gtk-2 one :]

Yap, I guess your right. I was probably just surprised.
Thanks anyway, and sorry for posting invalid bugs.

Although I still thing that kde4 kmail users could be surprised by that, too.
I think I'll stick with the qt4 pinentry version. ;)

Cheers
