I agree completely, Ben.

I don't understand at all how dev@oo.a.o became included in this, since it has 
nothing to do with development at Apache OpenOffice.

My reading of the quoted "narrow down" was as a suggestion for forensic 
purposes, the same way I test apparent problem documents with different 
products to see if there is anything in the pattern that gives me clue about 
what the defect might be.  And even so, there is no reason that the dev@ 
openoffice.apache.org list be cross-posted.

I am told that a document-forensic suggestion was not the intention.

In that case I want to make it clear that the ASF is completely ecumenical 
about open-source software projects, sees forking as a feature, and does not 
participate in advocacy of one project over another.  So, in accordance with 
the ASF operating as a US charity that provides free software as a public good, 
the Apache OpenOffice project does not concern itself about "rival software."  

Individuals have their own positions, sometimes rooted deeply in the past, and 
that shows up on various lists.  Those are not official positions, whatever the 
association of the advocate with Apache projects.

That the technical analysis on behalf of an issue on the Debian Bug Tracking 
System was used in this manner is unfortunate and regrettable.  It was also 
inappropriate that the dev@ openoffice.apache.org list was also so abused.

I trust we can remove the cross-posting now and Debian developers can return to 
their important business without this distraction.

Please, we don't need advocacy for rival software in the Debian BTS.

If ApacheOO solves the user's problem, then it is probably time for Debian
to reevaluate 'rival' alternative.

I don't understand the point of posting this message to dev@oo.a.o, especially 
with all the details of an apparent Linux problem in conjunction with 
LibreOffice (but not necessarily caused by LibreOffice).

I assume the recommendation of Apache OpenOffice is not as a substitute but to 
see if there is any forensic information to be gained by trying it too.  That's 
similar to why I compare AOO problems reported on .doc and .xls files in 
Microsoft Office and LibreOffice to see if there is anything different that is 
informative.

What did you have in mind, Jose?

You may want to *narrow down* your memory issue by trying out Apache OpenOffice:
