Hello,

we have similar case in Fedora 18
https://bugzilla.redhat.com/show_bug.cgi?id=922519

Description of problem:
I closed emacs with reboot purposes, but I am newbie, I don't know how to deal with emacs client and server together and I have not found proper guide, so It should be somtehing that related. Being Emacs-server still working at background probably receives the closing order as a kill signal. It's all what I know, by now...
If so what should I do?
Thanks.

Version-Release number of selected component:
emacs-24.2-6.fc18

Additional info:
backtrace_rating: 4
cmdline:        emacs --daemon
crash_function: style_changed_cb
executable:     /usr/bin/emacs-24.2
kernel:         3.8.2-206.fc18.i686
uid:            1000
