*** This bug has been marked as a duplicate of bug 302207 ***
Comment 2 Hrvoje Senjan 2012-06-20 07:01:02 UTC 
Robby, i urge you to not use my ppa, for now it holds post beta2 packages, but 
a): i also push other packages from master
b) KDE will soon be branched to 4.9, and i plan to trach master, not 4.9 branch, so it could get unstable.
Comment 3 Robby Engelmann 2012-06-20 07:17:17 UTC 
@Hrvoje
I planned to use your ppa until RC1 is released. And then I will stay with kubuntu/beta ppa.
But thanx for the hint.
