Description of problem:
Attempted to start empathy (from terminal or Gnome shell)
I had just updated some packages (notably zeitgeist and kernel) yesterday which I am guessing why it's segfaulting while starting up now, although I have seen miscellaneous, seemingly random, segfaults happen in the past.

Version-Release number of selected component:
empathy-3.10.3-1.fc20

Additional info:
reporter:       libreport-2.2.3
backtrace_rating: 4
cmdline:        empathy

runlevel:       N 5
