Mariadb Galera Cluster stack_bottom = 0x0 thread_stack 0x30000

I attached the complete terminal steps and the small tutorial I made. In /var/lib/mysql/kooka1h.err :

121005 15:18:22 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
121005 15:18:22 [ERROR] An old style --language value with language specific part detected: /usr/share/mysql/english/
121005 15:18:22 [ERROR] Use --lc-messages-dir without language specific part instead.
121005 15:18:22 [ERROR] mysqld got signal 11 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see http://kb.askmonty.org/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

Server version: 5.5.25-MariaDB
key_buffer_size=0
read_buffer_size=131072
max_used_connections=0
max_threads=153
thread_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 335099 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thread pointer: 0x0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
