Lock-up in the file browser on rename

[Biff]

Reprod as follows:

• Create a new virtual machine
• Add new storage attachment
• Choose 'add hard disk'
• Navigate to a file (pretty much any file or folder will do)
• Right-click 'rename'
• Hit backspace to remove the content of the filename so it is blank.
• Now click 'open'

A dialog is permanently displayed on the screen saying:

The name "" can not be used.

Try using another name, with fewer characters or no punctuation marks.

From this point there is no option but to kill VirtualBox.

it seems like this is reproducible. I will need to investigate this.

A work-around is that you can close the dialog using the 'x' at the top corner. So you don't have to kill VB, I was hasty in stating that. Still, the dialog has no option to 'cancel' only the 'OK' button and it isn't immediately obvious what to do. Clicking 'OK' produces the same dialog again.
