Kwallet system disabled in Kubuntu 15.10 but Kopete still uses it

Question

I have disabled the Kwallet system

But when I try to use Kopete messenger, it asks for a Kwallet password

Answer 1

The solution that worked (after disabling the service as seen in the image) was to remove

~/.config/kwalletrc
~/.kde4/share/apps/kwallet/* 
~/.kde4/share/config/kwalletrc

(as indicated in this answer)
