Hi,

Classical Extras throws this error:

```
Traceback (most recent call last):
  File "/usr/lib/python3.10/site-packages/picard/coverart/ __init__.py", line 144, in next_in_queue
provider = next(self.providers)
StopIteration

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3.10/site-packages/picard/album.py", line 314, in _finalize_loading_track

AttributeError: 'NoneType' object has no attribute 'split'

```

and it repeats for every track in every release added.

Picad About info: `Python 3.10.1, PyQt 5.15.6, Qt 5.15.2, Mutagen 1.45.1, Discid discid 1.2.0, libdiscid 0.6.2, astrcmp C, SSL OpenSSL 1.1.1m 14 Dec 2021`

Arch Linux.

Also, It doesn’t seem to be ‘configuration file’ related. Testing with a clean config has the same problem, with the same error.

The Classical Extras plugin is incompatible with Picard 2.7 and hasn’t been updated yet. See also [PICARD-2381](https://tickets.metabrainz.org/browse/PICARD-2381)

I am curious:

The Classical Extras plugin is an impressive piece of work and an important plugin for (I am guessing) many users.

I find it a bit strange that a new Picard version was released that breaks functionality, and the developers don’t seem to be concerned about Picard’s own role in that.

I am not sure that is sending a good message to plugin developers that are putting in a lot of time and effort in their work.

I have pushed a small fix for the Classical Extras plugin that resolves the crash. Version 2.0.14 should be available via plugin update now.

Thank you, It’s working fine again 😃
