Description of problem: I just installed F20 Beta TC1. After reboot and login, I noticed that dbus-daemon (running under gdm user) is eating 100% (8 minutes of CPU time already eaten). The process is: 1226 /bin/dbus-daemon --config-file=/etc/at-spi2/accessibility.conf --nofork --print-address 3 $ sudo pstack 1226 Thread 2 (Thread 0xb7428b40 (LWP 1229)): #0 0xb7736416 in __kernel_vsyscall () #1 0xb75933ab in poll () from /lib/libc.so.6 #2 0xb76c34ec in avc_netlink_receive.constprop.0 () from /lib/libselinux.so.1 #3 0xb76c39f1 in avc_netlink_loop () from /lib/libselinux.so.1 #4 0xb7675d8a in start_thread () from /lib/libpthread.so.0 #5 0xb759f9be in clone () from /lib/libc.so.6 Thread 1 (Thread 0xb7436780 (LWP 1226)): #0 0xb767f9e0 in __errno_location () from /lib/libpthread.so.0 #1 0xb777af82 in _dbus_babysitter_unref () #2 0xb773ea27 in bus_pending_activation_unref () #3 0xb776bc5e in _dbus_hash_table_unref () #4 0xb773ed81 in bus_activation_unref () #5 0xb7740c8b in bus_context_unref () #6 0xb773d0e0 in main () Version-Release number of selected component (if applicable): dbus-1.6.12-1.fc20.i686 gdm-3.10.0-1.fc20.i686 How reproducible: no idea Steps to Reproduce: 1. no idea, just happened
