I tested this with boiko a couple of days ago, and while i don't have his public key so that i could decrypt the messages, they looked correctly formatted in the window. (I was using an icq jabber gateway with psi at the time of receipt). liboscar does nothing to mangle the message. Are we sure this is even a valid bug?

Matt, how can you test whether kopete does mangle a message on receipt if you used a different application for receipt?

BTW: You can just test with your own PGP key. This bug does not depend on a specific key.

because the bug is about _sending_ messages from kopete, not receiving them.

Ah ok, so the description is misleading. In fact the mangling does happen on receiving.

if somebody could provide debug output, i _might_ take a stab at fixing this...

Yep, does happen on receipt.  Just sent an encrypted message from kopete to gaim and it was received as correctly formatted gpg 

still want/need debug output. knowing the client that is sending the message would also be useful. AFAICT, we do nothing to mangle the message on receipt.

THis is independent of the client used for sending. Tested with both, licq and kopete itself.

And now for the debug output of the receiving kopete:

judging from the debug output, this is not an ICQ bug.

Which component do you suspect then?

Note that it works for other protocols like Jabber.

*** Bug 101729 has been marked as a duplicate of this bug. ***

The problem also exists in groupwise... we are running the crypttext through the richtext processor, which breaks the crypttext of course.

There used to be a similar bug filed against the Jabber plugin, maybe it has been reassigned to the crypto plugin. Can't find it right now but the symptoms were exactly the same.

It works verry fine here, with both ICQ, MSN, and Jabber.

The problem is maybe in another plugin,  authoreplace, texteffect, ....
can you have a look ?

i have disable all plugins and the problem is still happen.

But have you the correct backtrace ?
doe it works with others contacts ? 
others protocols ?

what's your verison of kopete ?

It happens here too. Version 0.10 

There seems to be some kind of unescape on the message that removes line breaks (and html-tags).

I look through the code quickly the other day, and saw a reference (in protocols/oscarcontact.cpp) to the plainBody() method. My uneducated guess would that icq-messages are marked as RichText.. 

QString Message::plainBody() const
{
        QString body=d->body;
        if( d->format & RichText )
        {
                body = unescape( body );
        }
        return body;
}

unescape should work perfectly.
The problem is still in oscar.
I've found the Bug 102880.

*** This bug has been marked as a duplicate of 102880 ***

With 3.5, I've found another oscar issue with crypto.  PGP messages are split over two or more oscar messages.  Might it be worth checking incoming messages for BEGIN PGP MESSAGE without END PGP MESSAGE in ChatSession::append, buffering incomplete crypted messages and reassembling them?

won't / can't support use of cryptography over ICQ due to limitations in the protocol.
