Summary:
Transform bone constraint & 'local with parent' as owners space
Detailed description
If you have one bone with a transform constraint, and set its space to 'local with parent' it rotates or move weirdly. Even if all parameters are set to 0, (so no transformation should be applied).
And if you set the ifluence to 0 it moves ok. but with 0.001 does the same thing as with 1.000.

Passing back to you Joshua!
Here's patch that seems to fix this and #26014, but I must admit that the whole constraint system goes a bit above my head, so it's difficult for me to predict if this change will have any adverse effects. There seems to be something fishy going on in the space conversions on both bugs, but moving the influence interpolation outside the matrix conversions (so that the interpolation is always done in world space) seems to fix both bugs.
Please review the patch and decide what to do with these two bugs :)

Cheers for catching that! It seems to make sense.
