I have seen this bug and it abends my mh!  Luckily it only crops up when 
trying to set an IR_Item to an undefined state like this:

set $CABLE 'undefined_state';
set $CABLE 'power'; #if cable box has only discrete 'on' and 'off' states

So when you set up your IR devices, you must take note of the states 
(commands) supported for each item.  Your user code must not set an IR_Item to 
a state that does not exist for its device.

I think this module needs a little better error handling for this as the abend 
is pretty harsh for such a miscue...
