Calibre problems

That'll be good. Also, if the bugs get worked out of the Time epub conversion, that'll give even more flexibility.

One thing I've noticed is that in many of my epub conversions, the tables of contents seem a little problematic. Sometimes they work in the Calibre viewer but not on my 700, sometimes they work on my 700 but not consistently. I wonder if it's something in the conversion, or just bugginess in the Reader. Just now I was testing my own Calibre conversion of my own The Infinite Sea, and the ToC didn't work, and the Reader slowed waaayyyy down. I powered it off and back on, and it was fine again.

You mean the table of contents accessible by the menu or an embedded table of contents. Typically, problems that can be solved with a reboot of the reader indicate bugs in the reader.

Well...I've not done a systemic test, so I'm not sure. I've been puzzling over the two different tables and couldn't figure out whether they were two views of the same thing, or different tables altogether.

So I just tried my Calibre epub conversions of Sunborn and The Infinite Sea again. On the Reader, I can use the embedded ToC that I assume come from the mobi source file, at the front of the book. But the menu-accessible Contents pages are empty. In Calibre's viewer, I can use both kinds of contents pages.

Send me these epub files.

Sent PM. Can't remember how to attach files to a PM, though.

Well, here's The Infinite Sea. The Sunborn one I can't post publicly, because it's part of my "send me a receipt and I'll send you a free ebook" offer.

This one's up for free on my website, anyway.

I've downloaded .124, and while I haven't tested it yet for those Contents page problems on my own books, I did try a conversion of another long book (.prc) that had previously failed. This time Calibre produced an epub version, but it had some display problems, and attempting to use the Contents function on my Reader caused the Reader to freeze up.

I've opened a ticket and uploaded the files on the Calibre site.

It's never easy, is it?

The EPUB output will improve only as fast as I get get reports about problems with it. It took about 6 months for the LRF output to mature, I expect a longer period for the EPUB, since EPUB is a far more complex format.

[starrigger]

As long as I'm helping, not driving you crazy, by posting all these problems.

Ah, I guess I'm just bound and determined to test both your stability and Calibre's.

Just pushed it to the limit on a 4MB dictionary that I bought in mobipocket and deDRMed. This time I was converting to LRF. Alas, it did not work. Here's the error:

isinstance() arg 2 must be a class, type, or tuple of classes and types
Detailed traceback:
Traceback (most recent call last):
File "calibre\gui2\__init__.pyo", line 144, in dispatch

File "C:\Program Files\calibre\library.zip\calibre\parallel.py", line 618, in gui_text
TypeError: isinstance() arg 2 must be a class, type, or tuple of classes and types

Do you want me to email you the source file?

Hold off till the next release. I'm working on some more stability fixes. Try it with that and then if it doesn't work send it to me.

OK. One more data point: the deDRMed mobipocket file opens fine in Mobi Reader. It does not, however, open in the Calibre Viewer.

I get this error using 0.5.14. 0.5.13 did it as well. The book does not have any DRM. Mobipocket Reader can display this eBook just fine.

[kovidgoyal]

It's one of the MOBI books with "content encryption", search in the forums for that and you'll find out how to deDRM it
