Description kolAflash 2014-03-15 01:59:40 UTC
I can't send an PGP/Inline email to a receiver with an key I didn't sign before.

If I sign the receivers key before sending OR use PGP/MIME everything's working fine.

Reproducible: Always

Steps to Reproduce:
1. Create a new email.
2. Encrypt the email and set the encryption-format to PGP/Inline.
3. Click "Send".
Actual Results:  
KMail tells: It was not possible to create a message composer.

Expected Results:  
E-Mail should be encrypted and send using the PGP/Inline format.

I tried to find the bug searching in


Line 547
ValidTrustedOpenPGPEncryptionKey ) != item.keys.end() ) {  // -= trusted?
looks suspicious. I tried replacing it with:
ValidOpenPGPEncryptionKey ) != item.keys.end() ) {

Same for line 1575
NotValidTrustedOpenPGPEncryptionKey ); // -= trusted (see above, too)?
I replaced with
NotValidOpenPGPEncryptionKey );

But both didn't helped. I just got another error telling me, that the key is corrupt (it definitely isn't - I can use it for PGP/MIME and in Thunderbird it also works for PGP/Inline).

I modified keyresolver.cpp within the version 4.12.2. So please make sure that the problem occures at 4.12.2, too. See #328311

It's a little complicated for me, because my distribution (openSUSE 13.1) comes with KDE 4.11.4 and I don't like to play too much around with that system.

I'll try to set up a whole vm with KDE 4.12.2. But I don't have much time for gthat at the moment. (is there a ready-to-use KDE 4.12.2 livecd?)

Probably you could be much faster, trying what I described on your system. I'd be very happy if you could do so.

Tested it with openSUSE 13.1 + KDE 4.12.4 from this repo:


Result: Bug still exists in KDE 4.12.4 :-(

confired for serveral version now. Justto clearify it, what version of gnupg you are using?
Comment 8 kolAflash 2016-09-28 19:42:07 UTC
I'm using openSUSE 42.1 default software (KMail and GnuPG).
