Interestingly, I found that with the grantville gazette, a reset of the reader made the page turns all 1s again. The TOC page turns seem to be simply because the reader can't handle the large number of links. Do you have an LRF file with a large number of links in the TOC that has a quick page turn to the TOC?
One thing that was different about the grantville gazette was the large number of empty <a name> elements throughout the text. These get mapped to empty textblocks by html2lrf. Perhaps the resulting large number of textblocks is what the reader finds hard to handle. I'll look into that.
