[orca-list] Get stuck opening a page

[Francisco Javier Dorado <javier tiflolinux org>]

Hi all

When I open this spanish page Orca gets stuck at first link "Portada"

1. Open firefox and control + l,
 www.meneame.net
2. Press enter and wait until page loads complete.
3. Use down arrow and Orca gets stuck.

I have to say that when I alt + tab from Firefox and then come back and 
use down arrow again Orca works as expected and
doesn't get stuck.

Thanks,
Regards
Javier
