I have seen the panel segfaulting often after a shutdown, but this time also while I typed Ctrl-C, and by chance it can be the same problem. Here is the backtrace, I hope it can be useful: Program received signal SIGSEGV, Segmentation fault. 0xb7fa5af9 in client_session_set_restart_style () from /usr/local/lib/libxfcegui4.so.4 (gdb) bt #0 0xb7fa5af9 in client_session_set_restart_style () from /usr/local/lib/libxfcegui4.so.4 #1 0x08051386 in evaluate_run_state () #2 0x080517d8 in signal_pipe_io () #3 0xb787ab5d in g_io_unix_dispatch () from /usr/lib/libglib-2.0.so.0 #4 0xb7844311 in g_main_context_dispatch () from /usr/lib/libglib-2.0.so.0 #5 0xb78479a3 in g_main_context_iterate () from /usr/lib/libglib-2.0.so.0 #6 0xb7847ec2 in g_main_loop_run () from /usr/lib/libglib-2.0.so.0 #7 0xb7d0a729 in gtk_main () from /usr/lib/libgtk-x11-2.0.so.0 #8 0x08051d81 in panel_app_run () #9 0x08050056 in main ()
I trigger this bug inside Xephyr actually, not sure how it behaves under a normal X session.

FIx the crach in the shutdown action button in revision 29672.
Can't reproduce this bug anymore.
