[jadmin] Ubuntu Dapper and mu-conference

[Michael Wishart]

Ok, I installed jabberd2 on Ubuntu Dapper and it works fine, using the 
binary from http://packages.ubuntu.com/dapper/net/jabberd2. But when I 
followed the instructions in the Jabberd2 installation guide using jcr 
and mu-conference I get this:

~$ /usr/sbin/mu-conference -c /etc/jabberd2/muc-conf.xml
Jabber Component Runtime -- 0.2.4
2003-2004 Paul Curtis

Segmentation fault

I copy my muc-conf.xml and alias in router.xml below in case it helps. 
I'm not sure where to look for logs or anything else that may help.

muc-conf.xml

</jcr>

router.xml
....
<alias name='conference.mickwish.dyndns.org' target='linker'/>
....
I am wondering whether the seg fault is due to a Ubuntu Dapper specific 
issue of some kind, like file location or something. Can anyone help?

Thanks
