I am also seeing this on x86 with seamonkey, but not firefox. I haven't tried eclipse or any other xulrunner apps on 11.3 yet (see e.g. bug #623444). Debian, Arch, and Ubuntu all seem to have the same bug with cairo > 1.8.8 and xulrunner 1.9.1 or seamonkey.
If I've read the various bugs correctly, the reason the official binary doesn't crash is because it doesn't use --enable-system-cairo. If backporting the 1.9.2 fix doesn't work, perhaps this is a reasonable solution?
