Translating - error in original string

[Tiago Neiva]

What is the best place to post a correction to an original string?
In this case this one:

#: ../src/business/business-gnome/glade/payment.glade.h:13
msgid ""
"The invoice being paid.\n"
"\n"
"Note that is field is optional. If you leave it blank, GnuCash will
automatically assign the payment to the first unpaid invoice for this
company."

shoud be "...Note that THIS field is optoinal..."
