Strange things are happening with conversations' built-in ICQ protocol. After an update it refuses to connect, but if I'm logged in from my PC its client goes offline telling me that I've connected from another machine.

In advanced ICQ settings there is an option called Encryption, which is always set to "opportunistic_encryption"


If I leave this field blank, then press Done, then Save, then open the setting again - "opportunistic encryption" is there again.
