innobackupex-1.5.1: Error: mysql error: mysql: Unknown OS character set 'ISO-8859-15'

Hello,

I try to use xtrabackup on my Centos 6.2 x86_64 with mysql 5.5.20. The backup failed always with:

120201 10:49:22 innobackupex-1.5.1: Starting mysql with options: --defaults-file=’/etc/my.cnf’ --password=xxxxxxxx --user=‘root’ --unbuffered --120201 10:49:22 innobackupex-1.5.1: Connected to database with mysql child process (pid=3930)innobackupex-1.5.1: Error: mysql error: mysql: Unknown OS character set ‘ISO-8859-15’.mysql: Switching to the default character set ‘latin1’

locale:

[root@mydb1 ~]# localeLANG=de_DE@euroLC_CTYPE="de_DE@euro"LC_NUMERIC="de_DE@euro"LC_TIME="de_DE@euro"LC_COLLATE="de_DE@euro"LC_MONETARY="de_DE@euro"LC_MESSAGES="de_DE@euro"LC_PAPER="de_DE@euro"LC_NAME="de_DE@euro"LC_ADDRESS="de_DE@euro"LC_TELEPHONE="de_DE@euro"LC_MEASUREMENT="de_DE@euro"LC_IDENTIFICATION="de_DE@euro"LC_ALL=

I get the same with UTF8.

Where is my mistake?

Regards,
