Forwarding downstream bug: <a href="https://bugs.gentoo.org/show_bug.cgi?id=490414">https://bugs.gentoo.org/show_bug.cgi?id=490414</a>
When trying to switch resolution from 1280x800 to 1024x768 (using
xfce4-display-settings), I get a segmentation fault:
[ 6734.364] (II) intel(0): switch to mode <a href="mailto:1024x768@60.0">1024x768@60.0</a> on pipe 0 using LVDS1,
