Am using Firefox 2.0.0.5, but the problem started in previous versions (not sure which one). After upgrading to a fontconfig greater than 2.3.2-r1, Firefox would crash on many pages (e.g. http://en.wikipedia.org/wiki/Mozilla). Just a plain segfault. So I had masked all fontconfigs greater than that version. However, I accidentally upgraded to 2.4.2, and that is now the only one available in Portage - so I'm stuck with it. Way too many sites cause Firefox to crash. Any ideas? I'm not alone in this. Possibly Bugs 148145 and 118825 are related. Also, the folks on this forum thread had the same problem: http://forums.gentoo.org/viewtopic-t-564981-highlight-fontconfig+firefox.html Problem occurs even in safe mode. Konqueror shows them fine, though. Reproducible: Always Steps to Reproduce: 1.Upgrade to fontconfig-2.4.2 2.Use Firefox to go to Wikipedia's Mozilla page 3.See Firefox crash. Actual Results: Segfault. Expected Results: Should display it fine.

Created attachment 126835 [details] strace output of running (in safe mode). Attached an strace.
Just downloaded firefox-bin (not via Portage) - that works fine - at least in safe mode.
i forgot about the wrapper script. can you run strace directly against /usr/lib/mozilla-firefox/firefox-bin ? also run `gdb /usr/lib/mozilla-firefox/firefox-bin` then `run -safe-mode` cause the crash to happen, then `bt` you'll probably get the best results if you build firefox and freetype with -g in the CFLAGS and FEATURES="splitdebug". i know it takes a while to do that, so maybe just the strace for now.
Turned out the following bug was relevant and fixed my problem: http://bugs.gentoo.org/show_bug.cgi?id=187774 I never installed fonts manually, though. Don't know which font created the problem. I just did a recursive chmod.
