Debug file with show the VALUEERROR tracebacks

Dear Developers,

I experienced this issue under Ubuntu 12.10 awailable Orca version, possible need fixing this issue both master and gnome-3-6 branches:
When I goto www.atv.hu webpage and use h structural navigation command to jump between heading level links, some heading level links I partialy see braille output and not hear speech output if I goto next heading level. Braille output related problem I not Quantal verifyed, I looked braille output related problem my Ubuntu 12.04 system. Of course, the attached debug.out file I generated with Ubuntu Quantal.
Reproducation steps:
1. Launch Firefox, and open www.atv.hu webpage.
2. Search for example the"MSZP: 4-5 hónapja" text.
3. Press h key ciclical. You will be jumping some heading levels with Orca not producing speech output and only producing partialy braille output.

I analyzed the generated debug output. This "silent" heading levels Orca producing lot of ValueError: too many values to unpack (expected 2) exceptions.

Unfortunately, in Ubuntu Quantal I unable to test this problem with latest master branch version of Orca, because latest master branch version already require Python 3.3.

If very need, I will be try making a custom Ubuntu 13.04 local live build with containing latest master branch of Orca, but this is require more time. Original in Ubuntu 13.04 the 3.7.0.93-0ubuntu1 gnome-orca package version are awailable.

If this problem are already fixed master branch and gnome-3-6 branch Orca versions, excuse me the unneed bugreport.
