Firefox locale packages crash during installation

[maschino@jouy.inra.fr]

Hi,

I can't install mozilla-firefox-locale-* package on my hp workstation i2000.
I've tried mozilla-firefox-locale-fr-fr and mozilla-firefox-locale-de without
success. The error is:

-------------------------------------------------------------------------------
Selecting previously deselected package mozilla-firefox-locale-fr-fr.

Is this problem specific to IA-64 or does it affect other (64-bit) architectures
too?

Have a nice day
