Electrocute, destructible doors and You

Did a quick search, couldnt find anyone else reporting this yet, so here goes.

I've found that the Electrocute spell from the wizard will not break some destructible doors. The issue comes up depending on what side of the door you are facing. For help in explaining the bug, I made a picture and uploaded it here - http://i.imgur.com/8cgfs.png

If you are walking in a north-east or north-west direction, you are able to destroy the door as expected. However if you are walking in a south-east or south-western direction, coming up from "behind" the door graphic, the Electrocute spell will fail to destroy the door. The animation of the electrocute will actually stop short of the door as well. if you shift-click electrocute in the direction of the door, then the door will get destroyed.
