From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2) Gecko/20040803 Description of problem: Visiting the Canna web page, from the default US locale at least, causes Mozilla to crash with a segfault. I installed the debuginfo package and got a backtrace. The actual crash is in GetNormalLineHeight, layout/html/base/src/nsHTMLReflowState.cpp line 2124, because aFontMetrics is NULL. I will attach the backtrace. Version-Release number of selected component (if applicable): mozilla-1.7.2-0.2.0 How reproducible: Always Steps to Reproduce: 1.Start Mozilla in the default US locale 2.Visit the indicated URL 3. Actual Results: Mozilla segfaults. Expected Results: It should have shown me a page full of Japanese, or possibly some indication of missing fonts, as appropriate. Additional info:

Do you have some .fon fonts in your path? Or font files that aren't readable? This is the stack trace that's usually the result of one of those two things.
Which path am I checking? I looked in all the directories listed in /etc/X11/fs/config, and there are no .fon files in any of them. I also long listed all of those directories and verified that the read permission bits are turned on for ugo for all of them. Mozilla uses fontconfig, doesn't it? I have not edited anything in /etc/fonts, nor have I installed any fonts other than those in the Fedora Core 2 release. I do not have a ~/.fonts.conf. I updated to mozilla-1.7.3-0.2.0 today, and still have this problem. Thanks for your help.
I am experiencing the same crash described above except this happens when I browse to any site. I have a up2dated fedora 3. All was fine until I installed flashplayer and TTF fonts from my Windows partition. I've removed the flash plugin and the problem remains. Is there any way to track down which TTF font might be causing the problem?
This problem disappeared for me when I upgraded to Fedora Core 3. To solve your problem, try running ftlint on your TTF fonts.
Fedora Core 2 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC3 updates or in the FC4 test release, reopen and change the version to match.
I just noticed that this bug is still marked NEEDINFO. I have not encountered it in either FC3 or FC4. As far as I am concerned, you can close this bug.
So I believe this is a problem with installing bad fonts, and thus can't really be fixed by Fedora. Also, the original reporter hasn't encountered it recently. Closing.
