#68 Cannot delete bugs

[Anonymous]

when I'm trying to delete a bug it throws the error:
java.lang.Exception: Issue.java : update
impossible:java.sql.SQLException: Syntax error or
access violation, message from server: "You have an
error in your SQL syntax near 'issueTime FROM
issueTime,issueDetail WHERE
issueTime.issueDetailId=issueDetail.i' at line 1"

DELETE issueTime FROM issueTime,issueDetail WHERE
issueTime.issueDetailId=issueDetail.id AND
issueDetail.issueId=5

I'm running the system on Linux, Tomcat 5.5, MySql 3.*,
Java 1.5
