Here is a result List of the "Animated Filtercall" Tests.
  I tested all the listed PDB-Procedures
  that can be selected via the GAP's DB-Browser
  and the corresponding _iter_ALT Procedures
  on a 5-Layer Testimage with Menu.

   
  <Image>/Filter/Filter All Layers   using "Apply Varying" Button

   Test with PDB-Procedures (Plugins) that came with
   gimp release 2.0pre3
   and all the generated (or manually changed) _iter_ALT Procedures

State:
+ ... Passed simple "Apply Varying" Test OK
# ... Apply constant OK, but Apply Varying not possible (failed or has no LAST_VALUES buffer)
- ... Failed Test
. ... not tested

Additional notes:

(1)   the pagecurl plugin fails when called via
           <image>/Filters/Filter all Layers
      because it adds an extra layer for the curl to the image.
      
      pagecurl can be used as filter when called via
           <image>/Video/Frames Modify
      when Function: "Apply filter on layers" is selected as action.
      
      From my point of view it does not make much sense
      in animations,
      because this plugin works with fixed curling amount.



plug_in_map_object ol Testreport: (did not verfy that at the latest test)
   
   - The MapObject has an implicite feature:
     If the handled layer has NO ALPHA Channel (as backgrounds often do)
     and the "Transparent background" is ON
     it forces the creation of a new image.
     (regardless if the "Create new image" option is on or not)

     It took me hours to find out about that feature
     that looks more like a bug to me.
     I would prefere to add the alpha channel in such a case.
     
     If you want to do animated calls to MapObject ("Apply Varying" Button)
     please make sure that the background layer has an Alphachannel
     (Open Layers & Channels dialog, and "Add Apha Channel"
      to the bg layer)

  - If you call MapObject a 2nd time in the same gimp session
    gimp will crash if one of the drawables (that were used
    in the 1.st call) has become invalid.
    
    The BUG is in the GIMP-core Procedure(s)
       gimp_layer_get_image_id
       gimp_drawable_image_id
       
    (in older GIMP releases these Procedures did return -1
     on invalid Ids, in Gimp 1.1.3 it comes to a crash
     I hope that this Bug will be fixed in gimp 1.2)
