So, as usual, I answer my own question, sort of. The problem is that org exports the author text enclosed within a special directives, specifically:
(format "<text:initial-creator>%s</text:initial-creator>" author)) New line directives are not allowed within this declaration, it seems. Removing (manually) the initial-creator directive then works. So, my question would be: is this text:initial-creator tagging necessary? If not, can we remove it? The OpenDocument schema is vague about whether this is necessary. If we cannot remove it, i.e if initial-creator is required in the document, could it be put in separately (as a meta:initial-creator tag) so that the author field can be more general? I am *not* an ODT expert of any sort. But it is my route to Word documents when the need arises (which is luckily seldom). Anyway, no panic: I can simply manually edit the odt file just before the final processing...
