--- Comment #3 from t...@protonmail.com --- I'm not able to reproduce the exact same issue since I've accidentally deleted that appointment. I've tried it with another appointment, and I had one time the same error. I can't reproduce it now I've started it through the terminal. There is another error that I get, when I try to open the contact information of an upcomming birthday. He says that he can't find the contact, but when I look at my addressbook through Kontact, it is there like I expect.

I'm sorry for any delay in my response for this reason. -- You are receiving this mail because: You are watching all bug changes.
