Bug Description

For some reason, after enabling smart card authentication with pkcs11. gnome-settings-daemon would segfault, while looking for:

open("/usr/lib/pkcs11/", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

Because of the segfault, it would take up to ~15 seconds for the desktop to load after LightDM finised.

Installing the coolkey package (in universe), fixes these problems.

Thank you for your bug report:

- what version of Ubuntu do you use?
- how did you enable smart card authentification?
- could you get a stacktrace of the segfault with gdb?

This is on 12.04 LTS.

Authentication is enabled with "auth [success=3 default=ignore]" in /etc/pam.d/common-auth.

Stacktrace is:

Program received signal SIGSEGV, Segmentation fault.
