I am not getting the above error.
Can you please give me  some more info ?
Comment 2 Till Maas 2007-01-23 10:50:05 EST
What info do you need? It happens on both my desktop (AMD Sempron) and notebook
(Centrino), both i386 and running FC6. I installed it with yum install librfid
and when I run mifare-tool with no reader attached above error occurs. Don't
know whether or not it works with a attached reader since I don't have one
available atm.
Comment 3 kushaldas@gmail.com 2007-01-23 11:55:38 EST
But no errors coming in my Core Duo lappy in i386. Will ask other people also
Comment 4 Till Maas 2007-01-23 12:05:13 EST
A Pentium III with FC6 shows the error, too.
Comment 5 kushaldas@gmail.com 2007-04-24 06:29:47 EDT
Got it.
Asking the developers to look into it ..
Comment 6 kushaldas@gmail.com 2007-05-05 01:53:09 EDT
