Same thing here. I'm using Kopete 0.12.4 and it's not working with my friend using Kopete 0.12.3.
The problem is this:
- when I send him messages, they are correctly encrypted and he can decrypt them automatically;
- when he sends me messages, I see the PGP encrypted message and I've to decode it manually.
I'm using gpg 1.4.3.
Any clue?
