Public bug reported:
pcscd (1.8.10-1ubuntu1) crashed reproducibly in Ubuntu 14.04LTS when I remove
my Reiner SCT chipcard reader.
The reader uses the libifd-cyberjack6 driver. I tried with the driver version
from the Ubuntu repositories first, when
that failed I also tried with the ones provided from the manufacturer's
homepage, but pcscd crashes in both cases.
I ran pcscd in debug mode attached the chipcard reader, inserted and
removed the chipcard a couple of times and got this output:
/usr/share/doc/libusb-1.0-0 $ sudo pcscd -d -f

if I remove the reader while the card is inserted the log looks slightly
different, but pcscd still crashes:

pcscd also crashes if no card was inserted at any time while the reader
was attached.
I didn't experience this problem in 13.10
Please let me know, if I can help more to resolve this issue.
Cheers,
