[scribus] Problem with spanish characters Scribus-trunk

[Diego]

Hi; 

Sometime in the last 3 months I've lost the possibility to write some
spanish characters in text frames (I mean, tildes: i.e. manifestación,
campeón,...). Still I can do it using the text editor, or copy & paste
from LibreOffice.

Any idea about the problem and solution? Thanks!
