Comment # 1 on bug 1086723 from Egmont Koblinger

gconf dependency is used by the prefs migrator, which can be disabled at build
time (--disable-migration). (No idea of SUSE does so.)

gnome-terminal 3.28.x is the last series shipping this feature, the prefs
migration code and all remains of gconf were just dropped upstream in git
master (3.29.x).
