this may not strictly be a calibre-only issue but hoping for some clues. esp on how calibre imports / generates .ofp files

I have one frustrating epub novel which takes 20 30 secs to open on my Sony PRS-650. I have spent ages trying to trouble shoot. have converted the epub to txt & back again to remove any junk formatting, have reformatted my sony memory, bug persists only with this one book....

Inspecting the associated opf file in calibre library I see that it contains a huge chunk of text - basically a whole chapter of the book, included in the summary as a free extract.. I'm wondering if that can / should have an impact on opening time. the book opens fine on PC in calibre viewer.

if that is not the answer then I am truly as a loss as to what could survive an ebub to txt to epub conversion & live on to cause trouble ???

it seems that is the cause though: having deleted a big chunk of the metadata in calibre book summary pane, the book is now opening OK on Sony.

any insights gratefully received. I think I can attach the original .opf without breaching any copyrights , so here it is :

PS could someone also clarify how the original .ofp is getting into calibre.

I have a source folder(outside of calibre) with epub, .ofp & jpg files;
I delete the book completely from calibre , then I copy only the source epub file to my desktop & then drag it into calibre, yet it appears in calibre library with a full set of metadata.
So is that stuff also embedded in epub or is calibre finding old data because book was previously in calibre library ?

PPS if I delete metadata then use calibre to search for replacement metadata it find this:

and brings down that huge "free extract" of the book within the summary.

so is it "within spec" to have all that data in that file, and thus a ADE/Sony bug which causes the sony reader to choke on it, or is it a mis-use of metdata ?
