An example of $subject can be seen here:

I believe this is probably the same issue that Kevin
Field was reporting here:
http://archives.postgresql.org/message-id/200904171407(dot)n3HE7uri070869(at)wwwmaster(dot)postgresql(dot)org(dot)
For info, 0xC0000005 is a pretty general access violation error.
This turns what should be an easy link-click into a bit of a pain.
If people get more enthusiastic about referencing the archives by
message-ID it's going to become a real issue. Can we tighten that up?
I realize that message IDs are hard to tell from email addresses in
general, but if it's part of a URL I think we can assume it doesn't need
to be obscured.
