Would you be able to share the contents of the cache json? |
|
Probably the same as #1370 |
|
Could you run these lines in Python repl, and paste the output here? It might already be fixed in a newer version of Tk. |
|
Also try |

Thanks for the replies! Here's the cache json: Here's the output of those two lines: And here's the output of What's strange is that I had previously installed Porcupine, probably v2023.06.27, with no issues on this same computer. |

Porcupine is failing to determine which fonts are monospaced. This is used in the settings dialog. I know this is the problem, because there is a The logic for doing this was changed in #1421, between v2023.06.27 and v2024.02.07. I am also using Debian 12 on x86_64, so I might be able to reproduce this if I install the same fonts that you have. The problem is, you have a lot of fonts installed :) It would take quite a while for me to find and install them all. Instead, let's narrow it down by looping through the fonts in a way that keeps going even when the entire Python process crashes. Run this bash script and post the output here: #!/bin/bash
python3 -c '
import tkinter.font
tkinter.Tk()
print("\n".join(tkinter.font.families()))
' | sort -u | while read font; do
echo -n "Trying $font... "
if python3 -c "
import tkinter
from porcupine import settings
settings._dialog_content = tkinter.Tk()
settings._is_monospace('$font')
"; then
echo "ok"
else
echo "ERROR!!!"
fi
doneIn case I decide to install all fonts you have, please also run: I think this is the third or fourth time the monospace checking code causes this problem. Maybe I should do the entire check in a subprocess, so that I can handle errors better... |

Sorry, I posted a broken version of my bash script above. I edited my message and it now has a working script. |
Here's the output of the shell script:
Here's the output of that command:
What exactly is causing the Segmentation Fault though? |
Sorry, I forgot to mention that you need to have the venv activated for the script to work. Can you run it again after a
Looks good! I will try to reproduce the problem later today.
A bug in Tk. |
|
I can't reproduce this even after installing the same font packages that you have. But I will be able to fix this once I know which fonts cause crashing (that's what my bash script is supposed to check). |
Absolutely! Here's the new output: It stops on Amiri Quran Colored.
👍 |

I don't know why the bash script is stopping, so I rewrote it in python. Try running this Python script (with import sys
import tkinter.font
import subprocess
tkinter.Tk().withdraw()
for font in sorted(set(tkinter.font.families())):
print(f"Trying {font}...", end=" ", flush=True)
ret = subprocess.call([sys.executable, '-c', f'''
import tkinter
from porcupine import settings
settings._dialog_content = tkinter.Tk()
settings._is_monospace({font!r})
'''])
if ret == 0:
print("ok")
else:
print("ERROR!!!") |
Here's the output: "Amiri Quran Colored" is the only one it errors on. |
|
I released a fix. Try installing today's release and let me know if it works. You can delete the |
Sorry for the late reply! |
I get this output after following the Debian install instructions:
If you need any more info, just let me know!
