Comment(by redsweater):

 I altered the patch to be especially careful that the variables being
 initialized are set to the same default values they would have received
 previously. In particular, the problematic array lookups yield initial
 values of NULL, which I now set explicitly as the fallback value in case
 the array items don't exist.

 I switched from using "!empty" to "isset", so that the logic is identical
 to before: if the array element is set at all, it is used to initialize
 the variable. If it's not set, then NULL is used.  For categories, an
 empty array is the default initialized value, which matches previous
 behavior as well.
