bus error

[fmigpaulo]

Hi,
I've recently switched from (awesome) Ubuntu 9.1 to Ubuntu 10.x

My Ubuntu 10.1 experience was problematic (http://wwww.ubuntuforums.org/showthr...1601810&page=2).

After that, I decided to install a fresh copy of Ubuntu 10.04 with a diferent file system...
My laptop is an HP 530.

I'm troubled again, this time because of an bus error that prevents me from running gimp and software-center. Maybe this errors are connected!?

I've tried to reinstall software-center but i could't because of the same error that prevented me from starting it.

Here's what i've got from log/messages:

Can anyone please help me?

It's not really an emergency but i would like your opinion about getting a new hard drive.
