Version: 1.2 (using KDE 4.3.2) Installed from: Debian testing/unstable Packages 1. start Konversation with network 2. unplug your network (pour tea over your router or whatever) 3. wait a few minutes (not sure if that's important) 4. quit Konversation 5. repair your network connection 6. try to start Konversation Step 6 will fail because step 4 left a Konversation process running. You have to kill it first to have Konversation starting properly again.
Works fine now, so I guess it was fixed some time.
