Short description of error
When a bone is translated by an Action Constraint, its rotation pivot is broken.
Interestingly, when multiple action constraint are stacked on top of each other, it does seem to add the curves together correctly. For this reason I think the problem could be in the transform code, rather than the Action Constraint code.
Exact steps for others to reproduce the error
action_constraint_problems.blend
To see that the problem doens't seem to be with the Action Constraint itself:
