aeroo_ooo fails to convert merged table cells from oct to do

[nicoclavier]

aeroo for OpenERP V6:

The issue is the following :
Inside a header > frame > table : some cells are merged.
The conversion of the ODT file to DOC used to work as expected until recently, after re-installing the server with latest versions of all component (ubuntu 14.04 / OpenERP v6.0.4 / latest aeroo) : the merge instructions on cells of tables are ignored when converting to .doc

NB : the pdf document is fine.
Anyone has met this behavior ?

thanks for your time.
