builtins.KeyError: 'disk.num_blocks_cache_hits' log spam

[Etienne Dechamps]

My Deluge daemon is currently flooding its text output with:

15:21:04 [CRITICAL][twisted                       :147 ] Unhandled Error

builtins.KeyError: 'disk.num_blocks_cache_hits'

This is logged multiple times per second, resulting in massive flooding. This doesn't seem to impair the operation of Deluge itself though.

Running Debian Sid with package versions:

• deluge 2.0.3-3.1
• python3-twisted 22.2.0-1
• python3-libtorrent 2.0.5-6
• libtorrent-rasterbar2.0 2.0.5-6

I think I got the same bug, and the error keeps printing out whenever I use deluge-console or in the terminal I run deluged:

• deluged 2.0.3
• libtorrent: 2.0.5.0
• Python: 3.10.12
• OS: Linux TUXEDO OS 22.04 jammy

The installing source is from Tuxedo OS repo which is based on Ubuntu.
