copying database doesn't work

When copying a database in master (3.4-dev), I get the following error (both with JS enabled and disabled):

There seems to be an error in your SQL query. The MySQL server error output below, if there is any, may also help you in diagnosing the problem

ERROR: Unknown Punctuation String @ 184
STR: </
SQL: <span class="inner_sql"> CREATE TABLE `test4`.`Commentaar` ( `ID` int( 3 ) default NULL ,
`Commentaar` varchar( 53 ) default NULL ) ENGINE = MyISAM DEFAULT CHARSET = utf8</span>

SQL query:

<span class="inner_sql"> CREATE TABLE `test4`.`Commentaar` ( `ID` int( 3 ) default NULL , `Commentaar` varchar( 53 ) default NULL ) ENGINE = MyISAM DEFAULT CHARSET = utf8</span>
