%%%In a Python script, keyframe cannot be inserted/deleted for a single channel failing as follows:

k=bpy.data.meshes['face'].shape_keys.key_blocks['a']
k.keyframe_insert(data_path="value", frame=0)

Traceback (most recent call last):

File "<blender_console>", line 1, in <module>

TypeError: bpy_struct.keyframe_insert() index 0 was given while property "value" is not an array

k.keyframe_insert(data_path="value", index=-1, frame=0)

Traceback (most recent call last):

File "<blender_console>", line 1, in <module>

TypeError: bpy_struct.keyframe_insert() index 0 was given while property "value" is not an array

index=-1 doesn't work, because pyrna_struct_anim_args_parse() in bpy_rna_anim.c changes index=-1 to 0 and pyrna_struct_keyframe_parse() calls it twice, so the second call (index=0) throws the error.

Attached a patch (fix_anim_keyframe_parse_error.patch).

%%%thanks for the patch but infact there was no need to call the function twice, perhaps baddly applied patch, fixed r53505.%%%
