** Description changed:
I am on Ubuntu 10.10 with the default X server, and the following Python
code crashes it every time:
from Tkinter import *
f=Frame()
f.option_add('*font', "-family {DejaVu Sans} -size -25 -weight normal -slant
roman -underline 0 -overstrike 0")
f.pack()
text = StringVar(f)
entry = Entry(f, textvariable=text)
entry.pack()
text.set("a" * 600)
f.mainloop()
Unfortunately, I was not able to capture a backtrace with apport. I'm
using an Asus X58Lseries laptop which I believe is 1280 x 800 (WXGA)
using an Intel GMA X3100 graphics chipset. I have set System >
Preferences > Appearance > Fonts > Details > Resolution to 160 DPI for a
larger display.
