After 'M-x toggle-debug-on-quit', and quitting with C-g when you appear
to be in an infinite loop, you can keep pressing the key 'd', and the
debugger will single-step through the code.  It may be possible to see
where the infinite looping happens because you will see the same thing
happening over and over again.  Or it might get too boring, then type 'q'.

I actually noticed something of this infinite loop behaviour today,
and I have a glimmer of an inkling that it may be caused by the
function that tidies up links in task descriptions for planner-appt
[planner-appt-de-wiki].  I will have a look at this tomorrow to see if
my suspicions are confirmed.
