Description Max Schwarz 2019-07-30 21:06:47 UTC

From what I can see, there was a breaking ABI change in kcalcore (see https://phabricator.kde.org/D22697 ). This affects KMail (see below).
I guess all packages depending on kcalcore need to be rebuilt.

STEPS TO REPRODUCE
1. Use up-to-date KDE Neon Developer Stable
2. Try to launch kmail

OBSERVED RESULT
kmail: symbol lookup error: /usr/lib/x86_64-linux-gnu/libKF5MessageComposer.so.5: undefined symbol: _ZN8KCalCore9Incidence16staticMetaObjectE

EXPECTED RESULT
(KMail starts)

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 5.16.80
KDE Frameworks Version: 5.61.0
Qt Version: 5.12.3

Fixed in the last dev/stable updates.
