TypeError: 'NoneType' object is not iterable

On arch I get the following errors after installing through AUR:

Mea culpa. This should be working now. Just reinstall from the AUR.

Hi, just installed in fedora27 (with the necessary dependencies) when i came to the same error as above. I did a git update, ran setup again... but: still the same problem

@slartibart70 I'm not sure you got the fix I just pushed. That line should be at 261 now.

[slartibart70]

how can i clean/uninstall this thing? (for a new try)

[BasioMeusPuga]

I assume you used the python setup.py commands in the readme.

If you cloned the repo, type git pull in the root of your local copy. If you downloaded it as a zip, you'll need to download it again. After that it's the same procedure.

[slartibart70]

well, ok, did that already. And yes, must have been me ... now it doesn't show this error again. Therefore, another one when trying to open an ebup (i removed spaces in folder and filenames, still the same)

`Attempting to open: /scratch/xx.epub Exception in thread Thread-28: multiprocessing.pool.RemoteTraceback: """ Traceback (most recent call last): File "/usr/lib64/python3.6/multiprocessing/pool.py", line 119, in worker result = (True, func(*args, *kwds)) File "/usr/lib64/python3.6/multiprocessing/pool.py", line 44, in mapstar return list(map(args)) File "/usr/local/lib/python3.6/site-packages/lector/sorter.py", line 212, in read_book all_content = book_ref.get_contents() File "/usr/local/lib/python3.6/site-packages/lector/parsers/epub.py", line 63, in get_contents self.book_ref.parse_chapters(temp_dir=self.extract_path) File "/usr/local/lib/python3.6/site-packages/lector/ePub/read_epub.py", line 246, in parse_chapters chapter_data, self.book['split_chapters'][i]) File "/usr/local/lib/python3.6/site-packages/lector/ePub/read_epub.py", line 317, in get_split_content xml_string = this_split[1] IndexError: list index out of range """

The above exception was the direct cause of the following exception:

That's a book specific bug. If you don't mind, could you please link me to that epub? It helps to be able to see why things are happening.

[slartibart70]

i tried some other ebpubs and azw3 files. Sorry to say, but the "list index out of range" occurrs multiple times (with different epubs) and the whole app crashes after some time browsing pages in the (working and correctly displayed) ebooks. Pdf seems to work fine, though...

@slartibart70 I have fixed a similar bug. If that doesn't solve what you're experiencing, please open a new issue. Preferably with more information.
