I triggered it with Sigil set to create a blank ePub2 on open while testing epubveri. I then ran the ePub3-itizer plugin. When I opened the generated ePub3 file in Sigil and looked at the content.opf, the </spine> item appeared to be there and epubcheck did not complain though epubveri did complain about the missing </spine> item. If I opened the ePub3 file in 7-Zip and opened the content.opf in Notepad++, the </spine> item was not present. Any change made seems to fix the now you see me, now you don't </spine> item.
I've attached three files. The content_epub2.opf.txt is the original from Sigil's created blank ePub2, content_epub3_converted.opf.txt is from the converted to ePub3 file opened with 7-Zip and the content_epub3.opf.txt is what I see in Sigil when viewing the ePub3 content.opf.
