Actually, it's *probably* a bug somewhere deep in Qt/webkit.

I'd try some workarounds like intercepting the dialog close events and:
- deleting the web preview widget manually
or
- setting its html to a blank page

Hope that works. I understand how frustrating and time consuming
issues like this in the underlying libraries can be, and totally
sympathise with your pain.
