when I work much using xfce4-terminal, Evolution becomes unresponsive
and I need to reboot. Nothing else but Evolution is effected. This also
happens, if I don't run xfce4-terminal, but not that often.
$ pacman -Q evolution xfce4-terminal
evolution 3.8.3-1
xfce4-terminal 0.6.2-1
$ uname -rm
3.8.13-rt14-1-rt x86_64
