So I understand this is caused by the new version of davdroid? Because I hadn’t modified those contacts for a long time and before that update, I never had any problem.
It’s caused by an invalid VCard :); the new DAVdroid version just made the error visible.
If this is caused by Baïkal (which I haven’t updated for a long time), please tell me exactly what to report, because I’m not a devel at all
I don’t know where the invalid VCard comes from. Theoretically, a CardDAV server should send only valid VCards, but maybe it hast just stored and then delivered the VCard from another client.
