Comment 1 kushaldas@gmail.com 2007-01-23 15:32:06 UTC

I am not getting the above error.
Can you please give me  some more info ?

Comment 2 Till Maas 2007-01-23 15:50:05 UTC

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 16:55:38 UTC

But no errors coming in my Core Duo lappy in i386. Will ask other people also

Comment 4 Till Maas 2007-01-23 17:05:13 UTC

A Pentium III with FC6 shows the error, too.

Comment 5 kushaldas@gmail.com 2007-04-24 10:29:47 UTC

Got it.
Asking the developers to look into it ..

Comment 6 kushaldas@gmail.com 2007-05-05 05:53:09 UTC

Fixed in svn, will be in the nextrelease
