I also posted this as a Mozilla bug at https://bugzilla.mozilla.org/show_bug.cgi?id=271825. It might be related to bug#59849. I have net-www/mozilla-1.7.3-r3 compiled from source. net-www/mozilla-bin-1.7.3 works, but fonts get not antialiased. I tried unmasking and using freetype-2.6.9, but this did not solve the problem. The stack trace looks like this: #0 0xffffe410 in ?? () #1 0xbfffc1fc in ?? () #2 0x4a448800 in ?? () from /lib/libc.so.6 #3 0xbfffc058 in ??

OK, I found out that this bug is a dup of mozilla 183729, https://bugzilla.mozilla.org/show_bug.cgi?id=183729 The problem were some TTF files having mode 0400. Removing them solved the problem for me, and the crash itself is described and handled in this mozilla bug. So this bug here should be closed, but with wat resolution?
Should be fixed in >= 1.7.6, if that's not the case, you should reopen/comment on the upstream bug. https://bugzilla.mozilla.org/show_bug.cgi?id=180309
