rare error on some app (linux mint 32bits)

[DINAMIK]

Hi all,

I'm using linux mint 32bits (lisa - Oneiric) and yesterday, some app like mintinstall and the software manager stop working with this code

/usr/lib/linuxmint/mintInstall/mintinstall.py:252: SyntaxWarning: import * only allowed at module level
def get_status_description(self, transaction):
/usr/lib/linuxmint/mintInstall/mintinstall.py:260: SyntaxWarning: import * only allowed at module level
def get_role_description(self, transaction):
Traceback (most recent call last):
File "/usr/lib/linuxmint/mintInstall/mintinstall.py", line 6, in <module>
import gtk
File "/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py", line 40, in <module>
from gtk import _gtk
ImportError: /usr/lib/i386-linux-gnu/mesa/libGL.so.1: undefined symbol: xcb_glx_set_client_info_2arb

I meet some people on the same situation here https://answers.launchpad.net/ubuntu/+question/183731

and I discovered that them use the xorg ppa in order to have the open source drivers updated.

do you know how to solve this?

reinstalled the app that are failling but it doesn't work
I will perform a ppa purge... may it helps

thanks in advance
