[orca-list] Another freeze / getting stuck

[Francisco Javier Dorado <javier tiflolinux org>]

Hi all

I have found this freezing / getting stuck with the +1 button in many 
pages where this is implemented.

1. Open Firefox and press control + l, enter this url:
http://www.muylinux.com/2015/06/02/firefox-necesita-electrolisis
2. Press 1 to go to first heading
3. Press down arrow until  "Haz click aquí para hacer un +1 público" button
4. Press down arrow again, Orcas freezes and caret is stuck

The weird thing, is if you close Orca and load it the problem is not 
present until you load again the page.

Regards,
Javier
P.S. Yesterday I sent a debug.out file with a similar issue but mailman 
kept it for approval
