Kontact Settings>Show Extension Bar problem

[Liz Young]

Hi,

I'm seeking confirmation of this problem on Hoary:

Choosing the Distribution List editor in Kontact/Contacts works the first time 
with Settings>Show Extension Bar.  After switching to Mail, and then back to 
Contacts, the Show Extension Bar list is empty.  I can recreate this on every 
(re)launch of Kontact.

I managed to hang Kontact completely while testing this problem (not 
every time), and fixed that by removing kontactrc and restarting.  Launched 
from konsole shows this repeatedly until killed:

QButton::setState() / setOn: (unnamed) Only toggle buttons may be switched

I tried to recreate outside of Kontact, and hit another snag where Kmail 
Tools>Addressbook does nothing, and I have to launch it separately but once 
it's up Kaddressbook Settings>Show Extension Bar works as expected.

I looked on b.k.o, and there are similar issues (nothing exact).  Maybe it's  
fixed in 3.4.1?
