Error message when auto adding books

[Rachel]

Could somebody give me some information about the automatic book loading facility.

I downloaded 8:46 yesterday and was eager to try the automatic book loading. I pointed calibre to the directory with the new books, clicked apply and restarted calibre. I got the error message:

calibre, version 0.8.46
ERROR: Unhandled exception: <b>TypeError</b>:'int' object is not iterable

Traceback (most recent call last):
File "site-packages\calibre\gui2\auto_add.py", line 198, in add_to_db
TypeError: 'int' object is not iterable

I took some of the books out of the directory, restarted Calibre and got the same message. I put just one book in the directory and got it to load. I put another book in the directory and got the error message again. I restarted Calibre and tried one book and then two books more with success, and then the next time got the error message. Amongst the books, most were epubs which I do not need to convert, and there was one mobi which was converted automatically. I have had failure and success with the same file. This all seems quite inconsistent to me.

Can somebody translate the error message for me and give me some idea of what I need to do to get it to work consistently. Thank you.

Can't help with the message, But
Try turning OFF auto CONVERT. Preferences: Adding Books: Automatic Adding (tab)
un-tick the auto convert... Save

Then try it

That error is caused by a bug in 0.8.46 when auto-adding a book that has duplicates and you have turned on both duplicate checking and automatic conversion.
