[orca-list] Bug on Writer: Orca or LibreOffice?

[MENGUAL Jean-Philippe <texou actux eu org>]

Hi,

1st, I remember the facts: on Debian testing with MATE, orca 3.12, 
LibreOffice Writer 4.3, I try:
1. File -> Open, tab until File type combo box, arrow key to make it 
scroll. It doesn't work. To see the following item of the box, I need to 
do tab, shift-tab. In combo boxes such as Format -> Characters, I don't 
have this.
2. When I create a table, Orca doesn't tell me the cell coordinates. 
Instead, it gives me the whole line (e.g. A1, A2), regardless the cell 
where I am actually.

2nd: here's the debug file matching to all these tests:

My question: is it an Orca bug? can you reproduce it? is it a Writer 
bug? what kind of thing is a problem? is it at-spi?

Regards,
