Please describe the problem:
From Launchpad:
https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/387505
==========================

[Using Jaunty]

In Nautilus, at Edit->Preferences dialog, drop-down list items shows untranslated in my Spanish desktop. However, I can't translate it because they're not in the Launchpad template, which is fully translated as you can see here:

  https://translations.launchpad.net/ubuntu/jaunty/+source/nautilus/+pots/nautilus/es/+translate

For example, on Edit->Preferences, Preview tab, you can see "Local Files Only" and "Always" options, which can't be found in the template:

  https://translations.launchpad.net/ubuntu/jaunty/+source/nautilus/+pots/nautilus/es/+translate?batch=10&show=all&search=Local+Files+Only
  https://translations.launchpad.net/ubuntu/jaunty/+source/nautilus/+pots/nautilus/es/+translate?batch=10&show=all&search=Always

However, there are some other strings which are fully translated into Spanish and are displayed untranslated. For example, the "Icon View" and "By Name" strings can be seen (untranslated) on Edit->Preferences, View tab, albeit they're translated in Launchpad since some years ago:

  https://translations.launchpad.net/ubuntu/jaunty/+source/nautilus/+pots/nautilus/es/535/+translate
  https://translations.launchpad.net/ubuntu/jaunty/+source/nautilus/+pots/nautilus/es/539/+translate

and the translations are into the .mo file:

$ strings -eS /usr/share/locale-langpack/es/LC_MESSAGES/nautilus.mo | grep "Icon View\|Vista de icono"
<b>Icon View Defaults</b>
Icon View
Vista de icono
$ strings -eS /usr/share/locale-langpack/es/LC_MESSAGES/nautilus.mo | grep "By Name\|Por nombre"
By Name
Por nombre

I attach two screenshots to illustrate the problem.

Does this happen every time?
