[Koha] Update biblio record error

[Vitor Fernandes]

Hi there.

Today I tried to modify some biblio record and i get this error:

"Can't locate object method "delete_subfield" via package
"MARC::Field" at /usr/share/koha/lib/C4/Biblio.pm line 2852."

I've updated the MARC::Field by CPAN and tried to modify the record again.
What's wrong? Shouldn't the MARC::Field had that subroutine?

Cheers
