I have bought a Kobo Glo today. It has firmware 2.15, not the latest, as far as I understand.
I have a problem, I have connected it to Calibre (9.10, both 32 and 64 bit) and if I try to look into the device, I see that it stops after reading only 9 ebooks, and a pop-up comes out with this message
------------------------------------------------------------------------
calibre, version 0.9.10
ERROR: Unhandled exception: <b>TypeError</b>:sequence item 0: expected string, NoneType found

Traceback (most recent call last):
File "site-packages\calibre\gui2\library\models.py", line 1394, in data
TypeError: sequence item 0: expected string, NoneType found
------------------------------------------------------------------------

Before posting into the calibre forum, I would like to ask if anybody had a similar problem, not necessarily the same error code, but problems in connecting to Calibre. Could it be connected to the old firmware version ?

Thanks in advance.
