Created attachment 9705 thunar coredump Running Xfce built from git on Arch. Updated core components today and Xfce apps using exo segfault (xfce4-settings-manager, thunar). Git bisect leads to "Replace deprecated macro" as culprit. Attached are xfce4-settings-manager and thunar coredumps.

Thunar didn't crash on me, but xfce4-settings-manager did. Thanks for reporting!
