Once the 'Filter Expression' dialog has been opened then closed, it cannot be
opened again in the same instance of Wireshark.

Steps to reproduce:
1. Open Wireshark.
2. Click on the 'Expression...' button.
3. Close the 'Filter Expression' dialog (by any means).
4. Click on the 'Expression...' button again.
The 'Filter Expression' dialog does not re-open.

I suspect that the modification for bug ID 6472 may have something to do with
this: The file static variable 'window' remains non-NULL when the dialog is
destroyed, so preventing a new dialog being created?
