I recently ran into trouble with the KDE PIM Applications (KMail, Kontact, etc). They often hang or crash on startup or closure. A workaround is killing all akonadi related procresses.
I’m not sure weither this is a bug or caused by configuration or package mess up. My base system is Leap 41.1, but with updated Plasma and KDE Framework, KDE Applications and QT5. My repo list:
