Please bump the ebuild from 1.6rc_1 to 1.6 now that KOffice has been released. Cheers.
As carlo seems to be away, I'm on it now.
I'm not sure how far you're in the process of bumping, as this bug is still in the state ASSIGNED, but the ebuild has already been updated to 1.6.0 and the ChangeLog says 1.6.0 final as well. The final tarball of koffice-1.6.0 is different from 1.5.92, but the 1.6.0 final ebuild still references the tarball of 1.5.92.
Thanks for reporting, I forgot to test app-office/koffice itself (I'm using the split versions). Now fixed as of 1.6.0-r1.
Don't forget there is also app-i18n/koffice-i18n that needs updating.
