"Queue->CustomFields is deprecated, use Queue->TicketCustomFields instead" in RT 3.4.2

Hi there,

The following appears in my apache error log several times,

FastCGI: server “/usr/local/rt3/bin/mason_handler.fcgi” stderr:
Queue->CustomFields is deprecated, use Queue->TicketCustomFields
instead at /usr/local/rt3/lib/RT/Queue_Overlay.pm

I have searched on previous posts and the solution seems to be to
replace functions calls to CustomFields() with TicketCustomFields(),
however CustomFields() is not in the files it suggests.

I am using RT 3.4.2

Can anyone shed any light?

Regards

Brendan
