The error occures mostly when disconnecting or reconnecting the device. Please wait a few seconds after changing conection state. I am unsure if the deamon is stable over time when the connection state is unchanged. I found the service missing in various scenarios. After crashing I found the following entries in syslog:
Mar 23 14:13:51 einstein kernel: [ 560.029754] pcscd[2560]: segfault at 7f062128c248 ip 00007f062128c248 sp 00007f0620a5cee0 error 14 in libc-2.
Mar 23 14:14:30 einstein kernel: [ 599.765633] pcscd[2572]: segfault at 7f7840e4f248 ip 00007f7840e4f248 sp 00007f784061fee0 error 14 in libc-2.
I attached the crash report from /var/crash/
I can't find the attached /var/crash/ _usr_sbin_ pcscd.0. crash
I guess the crash occurs in the libifd-cyberjack6 driver and the bug should be reassigned to this package.
