This happens with anything: lpr, lpq, andy Gtk+ app when opening the print dialog, ... the problem is this:


  http->tls = SSL_new(context);
  SSL_set_bio(http->tls_credentials, bio, bio);

unfortunately at that point http->tls_credentials is still zero; this is a new feature implemented in 1.5.x series, which is why it worked before.
As far as I can tell GnuTLS should work, but I haven't tried it yet.

Is this still a problem with cups-1.5.2 ?

According to upstream fixed in cups-1.5.1.
