Package: python3-tk
Version: 3.10.5-1
Severity: normal
X-Debbugs-Cc: d...@shallowsky.com
Dear Maintainer,
When creating a Tk label with:
label = Label(frame, text=item, font=(item, 70)).pack()
Tk will dump core if the font is various Noto fonts, including
(but not limited to):
'Noto Kufi Arabic', 'Noto Looped Lao', 'Noto Mono',
'Noto Looped Lao UI', 'Noto Looped Thai',
'Noto Looped Thai UI', 'Noto Music',
'Noto Naskh Arabic', 'Noto Naskh Arabic UI',
'Noto Nastaliq Urdu', 'Noto Rashi Hebrew',
'Noto Sans', 'Noto Sans Adlam', 'Noto Sans Adlam Unjoined'
But the core dump only happens if the font list is sorted first.
If labels are created in the order that comes from font.families(),
there's no crash; if they're created in alphabetical order, crash.
I can get the font list from a python gtk3 program, sort the list
and display each font, so I don't think the bug is with the noto
fonts: they may have some sort of error, but gtk finds a way to
work around it and tkinter should at least not crash python; at
most it should raise an exception.
A minimal program to reproduce the problem:
==== BEGIN PROGRAM
from tkinter import Tk, font, Canvas, Frame, Label
root = Tk()
fonts = list(font.families())
# The crash only happens if you sort the font list:
# comment this out to see the full, but unsorted, font list.
fonts.sort()
def list_fonts(frame):
"""Show a list of font labels"""
for item in sorted(fonts):
print(item)
# Crash will happen on this line:
label = Label(frame, text=item, font=(item, 16)).pack()
canvas = Canvas(root, borderwidth=0, background="#ffffff")
frame = Frame(canvas, background="#ffffff")
list_fonts(frame)
==== END PROGRAM
The noto* packages I have installed are:
fonts-noto fonts-noto-color-emoji fonts-noto-core fonts-noto-mono
fonts-noto-ui-core
I installed python3.10-dbg libpython3.10-dbg python3-tk-dbg
