Strange dialog button when downloading members

[wimjongman]

When downloading a complete sourcefile into a directory where one or more members already exist, a confirmation dialog is presented. One of the buttons on this dialog is a copy of the message of the dialog.

I think this was caused by my own #2526

This is an issue.
