[libreoffice-accessibility] Office 3.6 and Orca 3.7

Hi everyone,

I am having difficulty with:
libreoffice_1:3.6.2~rc2-0ubuntu4_all.deb

The problem is that the Orca screen reader is not able to read cell 
coordinates in Calc as it used to back in OpenOfice. The Orca and at-spi 
versions I am using are:
gnome-orca_3.7.0.94-0ubuntu0.1_all.deb
and
at-spi2-core_2.6.1-0ubuntu0.1_i386.deb

The files that seem to be involved are:
/usr/lib/python3/dist-packages/orca/scripts/apps/soffice/speech_generator.py
/usr/lib/python3/dist-packages/orca/scripts/apps/soffice/braille_generator.py

Functions that have the bug:
def _generateRowHeader(self, obj, **args)
def _generateNewRowHeader(self, obj, **args)
def _generateColumnHeader(self, obj, **args)
def _generateNewColumnHeader(self, obj, **args)

Specific line in the code:
table in self._script.dynamicRowHeaders


In this line table is searched as a dictionary key:
self._script.dynamicRowHeaders


The expectation is that the keys be constant  whereas a variable of the 
table type is not.

So this error is generated:
type Table is unhashable

For this reason, apparently, Orca does not speak the cell info it should.

As this is fairly basic funcionality, I imagine someone has already 
figured it out. Can someone point me to the solution or patch?

Thanks,

Fernando
