Is there a way to trace signals?

[Skip Montanaro <skip pobox com>]

Is there a way to trace signal emission for debugging purposes?  I have
something I use from PyGTK which shims gobject.GObject, but that only works
for signals defined for subclasses of gobject.GObject which are written in
Python.  That's often enough, but sometimes it's not.  I was hoping there
was some configuration flag or environment variable I could set that would
allow me to do the same for g_signal_emit and friends without the overhead
of running my app under gdb and setting breakpoints and associated break
commands.

Thanks,
