Adding contact from Blackberry
If you add a contact from a Blackberry phone running BB10 the contact will be duplicated every time the device attempts to sync. The system works fine on the thunderbird SOGO connector and IOS, this is just a Blackberry issue.
The phones are a Blacberry Passport running 10.3.2.2474 and a Z10 running the same version.
I am running debian jessie and davical 1.1.4 as I needed to get rid of the ever appending semicolon issue.
UPDATE: I have just updated my phone to 10.3.2.2836 however upon testing with a new contact the problem remains.
