[Koha] Problem creating new marc structure in koha 2.2.6

[Pedro Faria]

Dear all,
I noticed some kind of a bug in the new koha 2.2.6. When I tried to
make my own marc structure named TEST I got this error (this is just a
piece of it...):

It says 'duplicate entry...' but I have no other structure with the
same name (I tryed many just in case...). So I got the new structure
but when I go try to add or remove some tags none appears.
