I want to send an email to Kevin Krammer but the "Contacts found in your data" popover suggests me three addresses it knows for kevin but all of them have his name and surname in lowercase
I can confirm this.
Fixed in http://commits.kde.org/kdepim/a4986fe40eb8c177058b88af0fd9edf5b1835c55 Unfortunately since i've now been lazy and some emails have been sent in lowercase some of my suggested emails is lowercase :/
