Yes, sorry I should have been more precise in my email.

mysql> select version();
+--------------------------+
| version() |
+--------------------------+
| 5.0.32-Debian_7etch5-log |
+--------------------------+
1 row in set (0.00 sec)

create table mytable2 ( label varchar(200) primary key ) charset latin1;
insert into mytable2 values ('Zorglub'), ('Zorglüb');
alter table mytable2 convert to character set utf8 collate utf8_general_ci;

this gives:
ERROR 1062 (23000): Duplicate entry 'Zorglüb' for key 1

I tried to search the changelog and the bug tracking system, but
without much luck.
Rgds,
