Downgrading korganizer from 4:4.8.5-0ubuntu0.1 back to the previous 4:4.8.4a-0ubuntu0.3 fixed the segfault.
In order to reach a consistent package dependency state, I also had to downgrade the following kde libraries (to the same versions as korganizer): libcalendarsupport4 libeventviews4 libincidenceeditorsng4 libkdepim4 libkdepimdbusinterfaces4 libkdgantt2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1052813 Title: korganizer segfaulting after Precise LTS upgrade 4:4.8.4a-0ubuntu0.3 -> 4:4.8.5-0ubuntu0.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kdepim/+bug/1052813/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
