STEPS TO REPRODUCE THE PROBLEM:
1. Open a skype (or other) chat
2. Write: "Mobile phone: +123456789987"
3. Press the send button
4. Tip and hold onto the number you wrote in step 2 in the chat protocol. A
context menu will appear.
5. Select "copy".
6. Open a contact
7. select "edit contact". The contact is getting editable.
8. select "add field"
9. select one of the phone number fields
10. Try to insert the phone number from step 5 using the keys [Ctrl] + [v]

EXPECTED OUTCOME:
1. An error message occurs because in step 5 not only the whole number but the
complete line of text (remember: "Mobile phone: +123456789987") was copied in
step 5. There was no possibility to select only a part of the text.
2. The complete string will be inserted but the user has to correct the sting
(numbers and '+' only) if he wants to save the contact.

ACTUAL OUTCOME:
Nothing happens. The user doesen't know whats going on.

REPRODUCIBILITY:
always

OTHER COMMENTS:
An a little bit better solution would be to inform the user that he could not
insert strings including non-numeric characters. But than the user has to
understand that the whole line was copied in step 5 and not only the number.
