The CSV sent by email contains 2 times the column name, and it contains empty lines, that break the publiposting.
Created attachment 3595 [details] [review] Proposed Patch
This patch doesn't seem to do anything, it sets and populates a value $content, but then that is not used. I think that line 592 should be changed from content => join( "\n", @output_chunks ) to content => $content Is that right?
I think you're right. We can cancel this patch (Nahuel has left BibLibre, and looking at the bug on our tracking platform does'nt help either, so...)
