Open eCard

Hi there,

I just got my new electronic ID card and tested the Open eCard App under Linux.
It's really nice that I can use the ID card without having to boot Windows in a VM, but I noticed a
strange behaviour of the eCard App:

I have a card reader with display and PIN pad and sometimes the app crashes with a segfault one or two
seconds after entering the PIN on the card reader, but not always...

Here is the terminal log from a crash:

Main class defined in config file.
mainclass=org.openecard.richclient.RichClient

I have attached the logfile generated by Java to this bug report.

During my tests, I always managed to authenicate using the nPA in the end, but sometimes I had to restart
the Open eCard App one or two times.

Do you have any idea about what causes this problems?
