SUMMARY

Some channels on Freenode have been set to +r, which means only logged in users can join the channel. Konversation's auto-join channel will fail on these channels.

STEPS TO REPRODUCE
1. Open Konversation.
2. Create a Freenode identity with a registered nick name.
3. Join #opensuse and set auto-join.
4. Restart Konversation.

OBSERVED RESULT

Auto join #opensuse failed, because joining channels happens before login.

EXPECTED RESULT

Auto join #opensuse works and joining channels happens after login.
