i am guessing it has something to do with the messages (<phone number>.db) in /home/nemo/.whatsup folder and the some id or key field in /home/user/whatsup-log file. i'll try and see if I can find the message that has that VCF contact attached and I will try to delete that message from the messages db. any help here?

btw, I tried importing a contact into my phone contact from whatsup and it gets stuck in Sailfish OS showing importing VCF with the rotating circle.
