I'd love to, if I knew how to launch the panel within valgrind (I actually
tried unsucessfully). The sad thing is that my quite dead battery doesn't
seem to be bouncing between not-present and present state anymore, so the
notification icon might well just stay still :( So even if I managed to run
the panel under valgrind, I wouldn't probably be able to reproduce the leak.

I'll try to look at the g-p-m code to see how it displays/undisplays the
notification icon to try to make a reduced testcase.
