Shall we forcibly disable svg until a proper fix is available? This issue has also been discussed in the forum: http://forums.gentoo.org/viewtopic-t-956738-start-0.html The suggestion was to disable a bunch of USE flags: USE="-svg -libnotify -xv -xcb" But only svg should be responsible for this segfault.
