As long as Author does not have an icon it does not exist ;)

That filter is also used by Words and calligraconvertor, so I am surprised 
that you feel so bound to it, sorry. Problem is also that there is no 
dedicated component for this filter (seems that is true for most?), and 
calligraauthor just has a "general" component, so how could I know :)

It crashed for two persons at least, with random documents. And when I looked 
at the algorithm it did not really make a perfect impression to me, also the 
bunch of warnings which you got when compiling. So it seemed a sane thing to 
just disable it for now, especially so close before a release when there is no 
proper time for investigation, fixing and testing. And a release is not the 
end, there will e.g. be 2.6.1 soon.

Also, I contacted the maintainer of the filter (moji) in the commit and once 
he pinged me on irc I helped him to find the problem, even if I had other 
things to do which are more important for me. Also pinged you about this the 
moment you appeared on irc.
I would do it like this again.

So proof there is not enough reason for now? :P

"Author 2.6" sounds like a mature application to me. But where is it in 
http://userbase.kde.org/Calligra and http://community.kde.org/Calligra ? Not 
existing :(

What is the purpose of releasing Author already now? What do people gain from 
it over Words? Sorry to hear you being a little bitter. But I miss the point. 
Actually I think we saved ourselves quite a few bug reports and disappointed 
users. Unless we are okay with an image "Calligra is failware".

And to show even more commitment here the result of a test against the test 
docs I pulled from boud's server (because "would be good" will not make it 
happen, so I did it, even if not maintainer):

testdocs/documents> ls *.{doc,docx,odt} -1 | wc -l
863

calligraconverter $f test.mobi  || echo "Failed for $f..." >> result.txt; done

Means the mobi filter possibly crashed in 13 of 863 files for me. With latest 
2.6. And most of the files I checked, got backtrace into mobi export filter.

I would disable it again, to be honest :)

Inge, could you run the test on your machine as well and compare? Then we can 
see which files Moji might be able to take to fix the remaining issue(s).
Anyone else interested is also welcome.

Moji, I will send the ones failing for me (listed above) to you, so you can 
give them a check. Or do you have a good internet connection and could simply 
download some 1.6 GB?

Cheers
