Created attachment 107744 [details] backtrace Reproducible steps: Add a contact to Kaddressbook. Compose an email in Kmail. Click select, while the address are loading it crashes. Remove the contact from Kaddressbook and "akonadaictl restart" corrects this. I have just recently installed Kubuntu and started using Kmail.
I can open KAddressBook and find a contact - it doesn't crash. Right now it crashes Kmail or Kontact whenever I use select in Kmail or Kontact.
