libpam-poldi crashes when device is in use

Attaching the output from "poldi-ctrl -d"

Version: 0.3.0-4 (in Feisty)

In my setup, I use libpam_poldi.so in the /etc/pam.d/common-auth file:

sufficient pam_poldi.so quiet
requisite pam_unix.so ...

Accessing the card via "gpg --card-status", for example, will cause any PAM Authentication to fail.

Furthermore, any other authentication done by the card, i.e. sending a signed message via enigmail, will cause pam_poldi.so to crash.

In order to regain PAM Authentication, I have to unplug, then plug back in, the USB Card Reader.

I am running the following smart card related applications (daemons):

pcscd
scdaemon
gpg-agent

I have not found a way to bypass pam_podi.so post-crash.

I have concluded that my problems are directly related to gpg-agent. I removed it.

pcscd is still running, scdaemon is not, gpg-agent is gone.

i can scan my card via gpg --card-status and login still works.

furthermore, i can pcsc_scan in the background, and login still works.

There is a new version of pam_poldi ( 0.4 ) available for the brave:

I got bored and gave up after 4 hours. Compilation wasn't the problem, it was the configuration and debugging.

It's supposed to use scdaemon for the backend, as opposed to checking a more difficult way. I was not able to
conclude if this resolves the bug.
