No, p3net.
I can't obtain a crashlog because I don't know how.
I saw SYSTEM - ADMINISTRATION - SYSTEM LOG on ubuntu feisty-fawn and there are nothing.
My OO has this configuration on my machine. Please, take a look:

I think that there are some incompatibility betwen openoffice.org-10n-pt or pt-br, or as you can see I'm using OpenOffice for Portuguese (Brazil).
I can (CAN) create a .doc file from OO but the problem that occurs is: I CAN'T open a .doc file.
This is a dramatic situation, because perhaps the only way to solve this is to install Ubuntu Feisty Fawn again, to recover Gnome and OO.
Any ways, really, I need some help.
Thank you all.
Ramiro.
