I don't want to use konversation-1.2_alpha<x>. While I appreciate the fact that konversation didn't slot very well, you either need to fix 1.1 so that it installs it's files somewhere that doesn't collide with 1.2 or just put 1.1 back in and remove the "slotting" from konversation so it doesn't try to install them side by side. A recent update broke my konversation 1.1 and now I can't rebuild it because the ebuild has been removed from the repository.
oh crap, I'm a liar. The problem actually is that revdep-rebuild called it konversation:0 and it didn't find a konversation in slot zero. The ebuild is still in the repo.
No worry then, we'll pretend you never filed this bug ;)
