Unity fails to include .bundle for native code plugin when building Intel Mac player.

When building the OSX player for my application on Unity 3.4 I run in to the following error:

Error building Player: IOException: Cannot create Temp/StagingArea/UnityPlayer.app/Contents/Plugins\jsbridge.bundle\jsbridge.bundle because a file with the same name already exists. UnityEditor.HostView:OnGUI()

Unity doesn't seem to use .dylib files if they're placed in the plugins directory, it only wants .bundle files so I'm lost on how to proceed, the documentation makes no mention of this issue.

This causes the player build to fail entirely, so I can't work around it by simply copying the .bundle to the folder in the .app bundle manually.
