When I receive a .vcf contact card in a SMS, and click on it, I am prompted the contacts account to save the contact to. If I choose the local phone contacts, or a gmail account, it works and the contact is imported. If I choose a DavDroid account, I get a message such as “The contacts app crashed” (this is a translation, maybe not the exact english error). The contact is not imported.
