For some reason, when gedit is run with strace, the dbus process gets started, but otherwise it doesn't. Perhaps this has to do with my system policy, I'm using permissions.secure and "restrictive" policykit permissions. jdf42@gari:~> gedit *** glibc detected *** gedit: malloc(): memory corruption: 0x00000000006fbaf0 *** ^C jdf42@gari:~> ps aux | grep jdf42 root 3212 0.1 0.0 107656 4996 ?
