mysql errors

I get the following when I try to run mysqlhotcopy on any of my databases.

[root@myhost]# /usr/bin/mysqlhotcopy -u root -p <password> -q <database> .

DBI::db=HASH(0x906da78)->disconnect invalidates 1 active statement handle (either destroy statement handles or call finish on them before disconnecting) at /usr/bin/mysqlhotcopy line 537.

Any thoughts?
