In file <koha-src>/misc/translator/po/es-ES-i-staff-t-prog-v-3002000.po
in line 2522 the original file says:
msgstr "(marco %)"
and it should say
msgstr "(marco %s)"
this causes translation install to fail strangely as it translates some of the templates but not all.
Thanks for reporting this bug. It is already corrected on the Koha
As today, you can see the valid translation here :

Don't stop translation installation even with wrong placeholder
This bug is mentioned in:
Bug 5740 Avoid stopping translation process when missing placeholder http://lists.koha-community.org/pipermail/koha-patches/2011-February/013827.html
It's a translation bug which hasn't its place in bugzilla.
