unix_chkpwd abnormal exit: 11 unix_chkpwd crashes under gnome-
screensaver and prevents unlock (/dev/null corruption?)

Bug description:
Binary package hint: libpam-modules
I am running Ubuntu Hardy 32-Bit on a Thinkpad T61 with all updates
available today. The gnome screensaver locks my screen after 10
minutes idle automatically. Now in the password dialogue I can enter
any password or string and the screen gets unlocked. In syslog you'll
find the following error message simultaneously:
kernel: [32810.156696] unix_chkpwd[4787] general protection
eip:b7f86446 esp:bfd2d31c error:0
But when I lock my screen manually, this bug doesn't occur and I have
to type the right password to unlock the screen again.
Some more informations:
