totem/help/Makefile.am's DOC_LINGUAS contains "bg", but totem/help/bg/bg.po file is missing. This makes the build fail:

make[2]: Entering directory `/opt/source/git/totem/build/help'
if ! test -d bg/; then mkdir bg/; fi
if [ -f "C/totem.xml" ]; then d="../"; else d="/opt/source/git/totem/build/../help/"; fi; \
	(cd bg/ && \
	  `which xml2po` -e -p \
	    "${d}bg/bg.po" \
	    "${d}C/totem.xml" > totem.xml.tmp && \
	    cp totem.xml.tmp totem.xml && rm -f totem.xml.tmp)
msgfmt: error while opening "/opt/source/git/totem/build/../help/bg/bg.po" for reading: No such file or directory

(I didn't file this under l10n:bg since "bg" was added to DOC_LINGUAS by the totem maintainer, not by the bg l10n team.)
