Hi,

I'am affected, too.

libselinux1 (2.1.9.5ubuntu1) has been installed when I installed apache. Since then 'sudo' quits with the error info above as posted by Ohadcn.

I use 12.10 32-bit.

The bug seems to be known elsewhere:

Thanks & Kind Regards,

With kernel 3.5.0-17-generic the problem doesn't occur whilst with the kernels 3.5.0-21-generic and 3.5.0-22-generic the problem occurs indeed!
