Which leads to:
http://hg.dovecot.org/dovecot-1.2/rev/4add5c3f13ea

Actually the fix looks slightly wrong to me, and it'll dereference a
NULL pointer in t_strdup_printf with openssl < 0.9.8. The setting of
comp_str to NULL if HAVE_SSL_COMPRESSION is not set should be changed
to setting comp_str to "" I believe.
