Traversing into subfolder when user tries to create a folder whose name already exists
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
In the file dialog when the user finishes editing the name of a new folder to create and presses return and a file/dir by that name already exists, they are prompted with an error message in a QMessageBox. But when they press this box's ok button or press return, the currently selected file/dir in the dialog gets activated.
