I am on Kubuntu 14.04 with KDE 4.13.0. Some days ago a request came in from someone I did not know. I deleted the contact without replying. However, they show up whenever I am offine under the group "Unsorted"

How do I delete this contact? I cannot right-click on the contact and if I try to delete the group the application crashes (it doesn't let me report the bug because the backtrace doesn't have enough info, it just says

Code: Select all

Application: KDE Telepathy Contact List (ktp-contactlist), signal: Segmentation fault

Any ideas? Many thanks!
