fnord hangs when serving images via https

Hi

When going to URL https://foo.localnet/img/foo.png, fnord hangs, whereas 
without ssl it serves the image.  What could be causing this?  Other 
files, including cgi's are served without problems.

.. using a tcpserver with the "a record", errno and nobase patches, 
together with André Oppermann's ssl/tls patch applied. I'm also using 
the same tcpserver for non-ssl connections. I've been using the same 
patched tcpserver for over a year on two hosts with a qmail pop3 service 
over ssl, so my guess is that tcpserver is probably not the culprit.

Any idea what's amiss?

Thanks
