After struggling a bit with my system, I managed to launch the ESC with a french Gemalto Smart Card & reader.

Here is what happens.

First I see a notification pop-up that tells me :
Can't get UniversalXPConnect.TypeError: Components.classes['@redhat.com/rhCoolKey;1'] is undefined

Then when hitting "diagnostics", I get the following.
SMART CARD DIAGNOSTICS REPORT

***Software Version Information***

 Smart Card Manager Version: null
 System Versions: mozilla/5.0 (x11; linux i686; rv:16.0) gecko/20100101 esc/1.1.0-16

***Active Smart Card Details***

  Number of Smart Cards Detected: 0


***Smart Card Activity***
No log file or log file has no data.


Can someone tell me what all this means (probably that the reader or card is unsupported), however...

Thanks
