196281 - Segmentation fault opening "Bookmarks" if one TrueType Font has no read access.

Status: RESOLVED DUPLICATE of bug 183729

(SeaMonkey :: Bookmarks & History, defect)

Description

[Danai Sae-Han]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4a) Gecko/20030305
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4a) Gecko/20030305

I have in directory "/usr/local/share/fonts/chinese/" the Chinese fonts
"fangzhengshutijianti.ttf" and "simsun.ttf", both owned by "root" but with the
rights set to "0400", so only root could read it.
Every time that I used mozilla-snapshot 1.3beta (for about a month now) on
Debian GNU/Linux, the browser crashed either within the first five minutes, or
it crashed immediately when I tried to access the Bookmarks (in the menu, or in
the Personal Toolbar).  When I accessed the bookmark editor using Ctrl+B,
mozilla-snapshot didn't crash for a few minutes.
I did a strace recently, and I found out that mozilla-snapshot crashed because
it couldn't read simsun.ttf.  I set it to "0644" and I can now access the
bookmars, and mozilla-snapshot hasn't crashed even once today.

Mind though that this problem didn't occur in Mozilla 1.2.1, so my guess is that
it has something to do with the FreeType2 engine.

Reproducible: Always

Steps to Reproduce:
1. set a font in your fontpath with rights "0400"
2. open the latest snapshot of Mozilla with at least one bookmark with a Chinese
title (traditional in my case, but I wouldn't be surprised if simplified has the
same problems)
3. hover to "Bookmarks" either in the menu or in the Personal Toolbar, and click
on it

Actual Results:  
Lo and behold: instant crash (on my computer at least ;)

Expected Results:  
Disregard the non-readable fonts, and use another one for Chinese characters.

I'm using:
 -Debian GNU/Linux, unstable.
 -mozilla-browser and mozilla-snapshot-browser packages

ccing Chris, but please test with a mozilla.org build -- debian makes some
"interesting" changes to their packages sometimes....

[Andrew Schultz]

is it an XFT build?  if so, this is a dupe of bug 183729

Comment 3

[Christopher Blizzard (:blizzard)]
