after .7.40, Calibre does show books on Kindle

[Ken Guenther]

After updating to 0.7.40, I continually get the following error message when I try to send a book to my Kindle (Kindle 2):
Traceback (most recent call last):
File "site-packages\calibre\gui2\__init__.py", line 306, in dispatch
File "site-packages\calibre\gui2\device.py", line 1180, in books_uploaded
File "site-packages\calibre\gui2\device.py", line 389, in add_books_to_metadata
File "site-packages\calibre\devices\usbms\driver.py", line 247, in add_books_to_metadata
AttributeError: 'list' object has no attribute 'add_book'

Calibre actually does send the book to the Kindle, but it still gives me the error message, and Calibre will not show any of my books on the Kindle.

any suggestions as to what to do?

That error message isn't very informative, can you run calibre in debug mode and post the debug log. Click the arrow next to preferences and select start in debug mode.

I am not sure the log file is very helpful either. But here it is.

Hmm well there is one bug in 0.7.40 that could possibly be causing this, fix will be in the next release (on Friday). In the meantime I suggest you downgrade to 0.7.38 available from https://sourceforge.net/projects/calibre/files/

[Ken Guenther]

Yes, reverting to 0.7.38 solved the problem.

[cybmole]

i think the thread title was intended to be 7.40 does not show....

anyway, I have 7.40 & it shows the books on my kindle 3 all OK

[chaley]

The bug is triggered by a condition that is never supposed to exist -- a book having no authors. The next release will have a check for it.

Workarounds:
1. revert to 0.7.38
2. ensure every book has an author. Search for authors:false and fix each book.

I'm getting this same error message on .7.40 with a Sony PRS-505. The books in question do have authors. Reverting to .7.35 seems to repair my problem.

It is triggered if any book in your library has no author, not just the one(s) you are sending.

First I get a RO-Kindle.

I do
sudo fsck.vfat -a /dev/sdc1

dosfsck 3.0.9, 31 Jan 2010, FAT32, LFN

/metadata.calibre
File size is 107532 bytes, cluster chain length is 16384 bytes.
Truncating file to 16384 bytes.
Unable to create unique name

Then I upload a book and get the error-msg.
After that I get again a RO-Kindle and the book on my Kindle.

Thanks for the very fast reply.

I finally succeeded with
>sudo fsck.vfat -r /dev/sdc1

the 'interactivery repair mode'

I'm glad you got it working.

Next time please open up a new thread.

Your problem wasn't anything like the original poster's problem. The original problem was corrected in version 0.7.41. Your problem was obviously a device level problem as evidenced by multiple OS/IO errors.
