Strange. I don't have a 5.5.30 build handy but I tried this on my
trunk build of mariadb using the sql command and it works:

ebergen@santa:(~/store/mysql/standalone_mariadb) ls -li mysql/slow.log
52430026 -rw-rw----. 1 ebergen ebergen 244 May 23 11:56 mysql/slow.log

ebergen@santa:(~/store/mysql/standalone_mariadb) mv mysql/slow.log{,.old}

ebergen@santa:(~/store/mysql/standalone_mariadb) ls -li mysql/slow.log
ls: cannot access mysql/slow.log: No such file or directory

ebergen@santa:(~/store/mysql/standalone_mariadb) ./con

Same with mysqladmin:
ebergen@santa:(~/store/mysql/standalone_mariadb) mv mysql/slow.log{,.old}

ebergen@santa:(~/store/mysql/standalone_mariadb) ls -li mysql/slow.log*
52430011 -rw-rw----. 1 ebergen ebergen 488 May 23 12:01 mysql/slow.log.old

ebergen@santa:(~/store/mysql/standalone_mariadb) mysqladmin -S
./mysql.sock flush-logs

ebergen@santa:(~/store/mysql/standalone_mariadb) ls -li mysql/slow.log*
52430026 -rw-rw----. 1 ebergen ebergen 244 May 23 12:02 mysql/slow.log
52430011 -rw-rw----. 1 ebergen ebergen 488 May 23 12:01 mysql/slow.log.old

Are you capturing errors from your crontab? Does running the command
by hand work?
