On your other questions:
> Were the programs you mention displayed in Catalan before the update?

They were in previous versions of Ubuntu. This is a program I compile myself and in previous versions once I had everything localized in Catalan in Ubuntu it would show up correctly in Catalan. Now unless I change the LANGUAGE variable as I explained above they will not show in Catalan.

> Exacly what did you do when updating? Are you referring to the distupgrade 24 days ago?

I was just referring to upgrading to 13.04 which I did some weeks ago.

> I suppose that you have a /usr/share/locale/ca_ES folder on your system with translations for those programs.

The strings for this program are actually in :

/usr/local/share/locale/ca_ES/LC_MESSAGES/
