This site loads fine with a CVS build I just pulled and built (on Linux, debug
build).  Do you have any plug-ins that could be causing trouble here?   I assume
you are getting the same "please log in" front page that I am before the crash?
 Or does Mozilla crash too early to tell?

1. too early to tell
2. seems to be related to font-handling

if I alter the fonts from the default sans/serif to a named font everything
seems to work

Could you please type "about:buildconfig" in the URL bar and hit enter?  That
should tell you the configuration of your build.  Was it configured with xft?

Comment 4

[redtux]

Configure with xft (both builds)

Do you know how to make a stack trace?

I have experienced the same thing under all XFT enabled builds of Firebird 0.7,
Mozilla 1.4.1, Mozilla 1.5, Mozilla 1.6 under Fedora Core 1.  Using non-XFT
enabled builds does not crash.  The following page is the culprit: 

http://msittig.freeshell.org/bookmarks/bookmarks.2003march.html

The Google cache of that page crashes the browser as well:

http://216.239.53.104/search?q=cache:umF5n-5uAxwJ:msittig.freeshell.org/bookmarks/bookmarks.2003march.html+sis+dvi+shuttle+xfree86&hl=en&ie=UTF-8

For some reason, If I run Mozilla or Firebird as root, I get similar behavior
visiting the site http://www.google.com .  If run under my normal account,
google does not crash, but many search result pages do.  The only variant I can
imagine there is my local user XFT configuration file, .fonts directory,
.xftcache, etc.  

I did not experience any crashes using XFT enabled builds under RedHat 8.0, and
these crashes only began appearing after upgrading to Fedora Core 1

I have some more information regarding this bug.  I strace'd the mozilla
process, and found the following right before the crash:

poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN, revents=POLLIN}], 2, 0) = 1
open("/usr/share/fonts/zh_CN/TrueType/zysong.ttf", O_RDONLY) = -1 ENOENT (No
such file or directory)
munmap(0xbf392000, 70121)               = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
unlink("/home/slacy/.mozilla/slacy/rsenavs6.slt/lock") = 0
exit_group(11)                          = ?

So, I went into /usr/share/fonts/zh_CN/TrueType and moved away the file
"fonts.cache-1" which was in that directory.  I also noted that the file
"zysong.ttf" did not exist.  I presume that these fonts.cache files were not
correctly upgraded from RH8.0 to Fedora Core 1.  I believe that by removing the
files, I am causing them to be regenerated.  It is possible that I'll have to
run some fontconfig program to add the fonts and recreate the fonts.cache files. 

After that, the page mentioned above loads correctly (and contains chinese
characters)
