When configuring Form Layout / List Layout / List type reports, expanding any reference field that references Configuration Item (cmdb_ci) causes the system to hang or perform very slowly.
Steps to Reproduce
Go to /incident_list.do.
Right-click in the table header and choose Configure > List Layout.
Expand the Configuration Item field.
Note that either the page hangs or the field expands only after a long delay.
