Error when taking a ticket

On a ticket page, I clicked on the link “Take” and get the following error.
The ticket is suspect anyway because it lost its original subject and I
found it in a wrong queue. It has been imported from rt2, so this may
indicate a buggy import.

Regards Dirk.

Can’t call method “Delete” on an undefined value at
/export/rt3/lib/RT/Ticket_Overlay.pm line 3049.
