207773 - Xft build crashes on specific url with Code2000/Code2001 installed [@ XftCharIndex]

Status: RESOLVED DUPLICATE of bug 183729

(Core Graveyard :: GFX, defect)

Description

[Christian :Biesinger (don't email me, ping me on IRC)]

If Code2000 or Code2001 is installed (from http://home.att.net/~jameskass/) my
Xft (both gtk1 and gtk2) build crashes when I load the above url.

This is due to GetXftFont returning NULL, called from nsFontXft::GetWidth32.

Here's the stack:

Comment 1

[Christopher Blizzard (:blizzard)]

This is probably a dup of bug 183729.

Comment 2

[Christian :Biesinger (don't email me, ping me on IRC)]

oh _damn_, you are right. I did notice that bug while searching if this was
filed, but it didn't occur to me to check world-readability. so sorry for
wasting your time.

marking as duplicate.
