After the Pangolin upgrades from 19. September korganizer will start and crash immediately.
In order to have symbols in korganizer's stracktrace I've installed the following additional packages:
libqt4-dbg akonadi-dbg kde-runtime-dbg kdepim-runtime-dbg
This is what KDE's crash reporter says:
Application: KOrganizer (korganizer), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I've also reported the bug to KDE here: https://bugs.kde.org/show_bug.cgi?id=307026
Might be that this might be the same problem as this one here within Linux Mint: https://bugs.kde.org/show_bug.cgi?id=298132
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 torsng4 terfaces4
libeventviews4
libincidenceedi
libkdepim4
libkdepimdbusin
libkdgantt2
