Comment:

 Possibly related, but certainly a side effect
 [http://wordpress.org/support/topic/yet-another-category_id-how-to-
 thread?replies=1]

 Multiple issues surfacing -

 $category = get_the_category();  = fails to get the category ID numbers
 echo $category[0]->cat_name;  = (tested on two different servers now) the
 " -> " is being read as the closer for a " <!-- " HTML comment tag.

 The context I'm trying to use this in, is in the sidebar, in a widget, to
 grab the category ID number and assign it to a variable for use in a
 function call.  In this instance, it's a new build where the category
 number, Adrotate group and block, and the NextGEN gallery ID numbers are
 all synchronised such that ID 1 = name Art in all cases.  But, the
 category ID call is failing and blocking the build from progressing.

 I'm not submitting this as a support shout, but rather to give you an
 instance of failure.  The initial ticket report now gives me a clue as to
 why.
