Comment # 1 on bug 932570 from Bj�rn Lie

ctrl + c -> shift + ctrl + v works just fine here.

If you by copy paste mean "Highligh" and "paste" via left and middle-click,
note that in order to copy an url you need to tap/click left-button 3 times to
do a "copy" from the url field. The initial highlighting is ignored.

Does the above solve your problem?
