Cash with "Could not load fallback font, bailing out."

Post by vonProteus »

I'm running Mac OS 15.6.1 (arm64).
I have Deluge (a thin client) installed in a virtual environment.
I created the venv using the following command:

Code: Select all

$ cd $(mktemp -d)
$ python3 -m venv venv && source venv/bin/activate
$ python3 --version
Python 3.13.7
$ pip install deluge==2.2.0 rencode==1.0.6 PyGObject
Collecting deluge

When I run it with deluge-gtk, I get the following error:

  import pkg_resources

zsh: trace trap  deluge-gtk
What's interesting (at least to me) is that the errors occur after I click "Connect," and then I can see the torrents list and crash immediately.

So, what can I do to fix this font issue?
