Re: Lenya 2.0.3 publication went haywire, please help

Hello Petteri,

Seems to be a good "bug case"...

Some ideas after reading your log.

I remember a bug around "language" when remove a document (solved). I 
don't have time to find right now this bug but with a search on archive, 
you may find it. This was solved in 2.0.4 if I well remember.

Another remark : this document may seems to not exist : 
lenya://lenya/pubs/hzc/content/authoring/0d10b9c0-171b-11df-ba0b-d3efee27d289/fi
