1. Create a new bazaar repository.
2. Create a file inside this repository.
3. Open the file in Creator.
4. Select "Tools" -> "Bazaar" -> "Commit..." from the menu.
   The Commit Editor will show up. It does not show a user name. Of course, how could it know one?
5. Enter values for "Author", "Email" and "Description" and click "Commit x/x File(s)".
   The commit will fail with the following error message in Version Control View:

   13:53 Executing in /tmp/untitled2: /usr/bin/bzr commit --author=Robert Löhning <robert.loehning@digia.com> -F /tmp/QtCreator.X24112 deployment.pri main.cpp main.qml qml.qrc untitled2.pro
   bzr: ERROR: Unable to determine your name.
   Please, set your name with the 'whoami' command.
   E.g. bzr whoami "Your Name <name@example.com>"
   The command '/usr/bin/bzr' terminated with exit code 3.
   

Creator should be able to create a commit with the entered values.
