Summary:                    mod_gnutls 0.5.x crashes Apache on startup
Description: 
With mod_gnutls 0.5.0 or 0.5.1, Apache crashes on startup.  Errors are
dumped to the error_log (see Additional Info. section).

This is with Apache/2.2.8 on Linux, with other modules DAV/2 PHP/5.2.5
SVN/1.4.2 also running.

I have gnutls 2.2.1 installed and APR memcache 0.7.0.  mod_gnutls was
simply configured as follows and compiled with no extra CFLAGS:
  ./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc

mod_gnutls 0.2.0 seemed to work well.

I wish I could provide more info. but I'm not sure what would help to
diagnose this.  Please let me know what would be useful.

Does this also occur with 0.4.3? Try running apache on a single process
with gdb to see why this fails. Also try to disable features (ie
apr_memcache)

Hi,

I found something else which I hadn't previously noticed -- this message
was appearing in the error_log of a virtual host when attempting to start
apache2 with mod_gnutls 0.5.1:
  GnuTLS: Host 'www.example.com:443' is missing the GnuTLSPriorities
directive!

After adding that directive to all of my HTTPS virtual hosts, everything
seems fine; there is no longer a crash on startup and both HTTP and HTTPS
are functioning.

I tried creating a fresh set of apache2 configuration files to try and
reproduce the crash, but I found that the above GnuTLSPriorities error
would appear in the virtual host error_log with *no* output to the main
apache2 error_log (and no crash either, I believe).

If you think it's worth doing, I could spend more time trying to find out
the exact cause of the crash, but since this was probably only happening
when the required GnuTLSPriorities directive was missing then it's maybe
not important?

Thanks.

This crash is quite strange. After printing this error message mod_gnutls
forces apache to exit. Which apache are you using?
