What were you doing when this happened? Can you duplicate it?
I tried to close the Midori browser which was not responding (probably because of Flash). In the end xfwm crashed and Midori kept running. I tried again a couple of minutes later and the same thing happened.
I started gdb on a running xfwm4 process and it gave me this which seems similar to the backtrace computed by ABRT: Thread 1 (Thread 0x7f55f7990a40 (LWP 4440)): #0 0x0000003455aeb750 in __poll_nocancel () at ../sysdeps/unix/syscall-template.S:81 No locals. #1 0x0000003457e480f4 in g_main_context_poll (priority=2147483647, n_fds=4, fds=0x2028040, timeout=-1, context=0x1eb0cb0) at gmain.c:3995 poll_func = 0x3457e56d50 <g_poll> #2 g_main_context_iterate (context=0x1eb0cb0, block=block@entry=1, dispatch=dispatch@entry=1, self=<optimized out>) at gmain.c:3696 max_priority = 2147483647 timeout = -1 some_ready = <optimized out> nfds = 4 allocated_nfds = 4 fds = 0x2028040 #3 0x0000003457e4855a in g_main_loop_run (loop=0x2027fb0) at gmain.c:3895 __PRETTY_FUNCTION__ = "g_main_loop_run" #4 0x0000003cef33fdb7 in IA__gtk_main () at gtkmain.c:1257 tmp_list = 0x0 functions = 0x0 init = <optimized out> loop = 0x2027fb0 #5 0x000000000040b6c9 in main (argc=1, argv=0x7fff68a4a8a8) at main.c:627 daemon_mode = 0 version = 0 replace_wm = 0 context = <optimized out> error = 0x0 option_entries = {{long_name = 0x43ff31 "daemon", short_name = 0 '\000', flags = 0, arg = G_OPTION_ARG_NONE, arg_data = 0x7fff68a4a68c, description = 0x43ff38 "Fork to the background", arg_description = 0x0}, {long_name = 0x43ff4f "compositor", short_name = 0 '\000', flags = 0, arg = G_OPTION_ARG_CALLBACK, arg_data = 0x423040 <compositor_callback>, description = 0x43ff5a "Set the compositor mode", arg_description = 0x43ff72 "on|off|auto"}, {long_name = 0x43ff7e "replace", short_name = 0 '\000', flags = 0, arg = G_OPTION_ARG_NONE, arg_data = 0x7fff68a4a694, description = 0x43fbd8 "Replace the existing window manager", arg_description = 0x0}, {long_name = 0x43ff86 "version", short_name = 86 'V', flags = 0, arg = G_OPTION_ARG_NONE, arg_data = 0x7fff68a4a690, description = 0x43fc00 "Print version information and exit", arg_description = 0x0}, {long_name = 0x0, short_name = 0 '\000', flags = 0, arg = G_OPTION_ARG_NONE, arg_data = 0x0, description = 0x0, arg_description = 0x0}} Continuing.

ok, nothing obviously is leaping out at me there. Would you be willing to file this upstream at bugzilla.xfce.org? Or would you like me to do so?
This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
It's still happening with xfwm4-4.10.1-2.fc20.x86_64.

Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
