3 rows in set (0.01 sec)

$ cat /usr/local/mysql/mysql-bin.index
./mysql-bin.000055
./mysql-bin.000056
./mysql-bin.000057

So all seems fine. Actually, I have taken this question to mysql list
and found out that other users are reporting similar problems.

http://lists.mysql.com/mysql/206576
http://bugs.mysql.com/bug.php?id=28238
http://lists.mysql.com/mysql/202793

So my final solution (if anyone's interested) was adding this to crontab

11      11      *       *       *       /usr/local/bin/mysql -u root
-psecret -e "PURGE MASTER LOGS BEFORE DATE_SUB(CURRENT_DATE, INTERVAL
7 DAY)"

It works so no problem but I do not really like the idea of providing
passwords in crontab. I wish the option in my.cnf file worked as
advertised.

Anyway, thank you very much for your help.
