Due to this, there's no localization on brasero 2.26

I solved it here by comparing the Makefile.in.in on the /po directory with the same file on eog package.

This is how it is:

USER_LINGUAS=$(shell if test -n "$(LINGUAS)"; then LLINGUAS="$(LINGUAS)"; ALINGUAS="$(ALL_LINGUAS)"; for lang in $$LLINGUAS; do if test -n "`grep '^$$lang$$' $(srcdir)/LINGUAS 2>/dev/null`" -o -n "`echo $$ALINGUAS|tr ' ' '\n'|grep '^$$lang$$'`"; then printf "$$lang "; fi; done; fi)


and this is how it should be (how it is on eog):

USER_LINGUAS=$(shell if test -n "$(LINGUAS)"; then LLINGUAS="$(LINGUAS)"; ALINGUAS="$(ALL_LINGUAS)"; for lang in $$LLINGUAS; do if test -n "`grep ^$$lang$$ $(srcdir)/LINGUAS 2>/dev/null`" -o -n "`echo $$ALINGUAS|tr ' ' '\n'|grep ^$$lang$$`"; then printf "$$lang "; fi; done; fi)


notice the single quotes on  grep '^$$lang$$'`"
well, by replacing one by another the problem was solved, so that's it
