Description Kamil Páral 2013-10-08 08:01:13 UTC 
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
