Description Martin Steigerwald 2013-09-16 14:39:13 UTC

Since "[Bug 44699] can't encrypt with gpg if the receiver's key is not signed" is fixed, KMail allows to send mails to untrusted keys. This worked for quite some time.

But recently I needed to send to untrusted key again and after confirming to KMail that I want to use that untrusted key, entered the passphrase I got a general error message that doesn´t tell much about the cause of the error.

Setting the key trust to fully trusted makes KMail sign and encrypt the mail just fine.

This has security implications as it user can only work-around it by setting a key to trusted they may not have had a chance to verify yet.

This might be a duplicate of

Bug 322708 - kmail should allow encrypting mails with keys of unknown/zero trust 

but since this bug doesn´t contain any detailed information, I don´t know for sure.

Reproducible: Always

Steps to Reproduce:
1. Sign and encrypt mail to a key that you do not fully trust.
2. Tell KMail to use that key nonetheless.
3. Enter your GPG key passphrase.
Actual Results:  
"Fehler beim Erstellen der Nachricht: Allgemeiner Fehler"

translated: "Error while creating mail: General error"

Expected Results:  
1) Sending to uncrypted mails works.

2) Any occurence of "general error" is replaced by an error message that is more descriptive than that (I can file another bug report for that one if needed)

I can confirm this bug. (KMail 4.10.5)

Comment 2 Sandro Knauß 2014-03-30 17:33:28 UTC

can you reproduce this bug in 4.12.2? So maybe it is a duplicate of Bug 328311, that is fixed within 4.12.2.

I just triaged this bug, and the feature now works as intended: When I select a non-trusted key for a recipient, a warning is shown when sending, but I can decide to encrypt to that key anyway.

I'm on KMail 5.2.3 from Debian stretch.
