I usually put statements like

    fprintf(stderr, "Got this far, task %p added\n", task_pointer);

into C code to see what it is doing until a better understanding of the
problem emerges.

I think those add debugging info for tools like gdb and valgrind to show
you file and line number of where a problem occurrs. I find them most
useful for debugging segmentation faults and detecting uninitialized
variables.

For this particular case I ran xfce4-power-manager with cinnamon (Mint's
version of Gnome 3), and I observed the same problem with ghost-icons in
the systray after suspend-and-resume. This makes me think the problem is
in x-p-m.
