Debugging log

I see this error when trying to debug "nautilus", the file manager from GNOME.
Putting a breakpoint on "gtk_window_size_allocate" and then typing "n" to
advance when the breakpoint is hit is enough to reproduce.

$ gdb --version
GNU gdb (GDB) Fedora 7.8-20.fc21

Debugging log file with "set debug infrun 1" and "set debug lin-lwp 1" set
attached.
