System Information
Ubuntu 14.04
MD Mobility Radeon HD 5000 Series

Blender Version
Broken: 2.74

Short description of error
After the object is deleted from the scene, if there were existing shape keys added to the object they are not removed from bpy.data.shape_keys collection. bpy.data.shape_keys['Key'].users is 0, however bpy.data.shape_keys['Key'].user points to
bpy.data.meshes['Cube'] (for ex.)

If all shape keys are removed from the object ( bpy.ops.object.shape_key_remove(all=True) ) before deleting it, the bpy.data.shape_keys collection is correctly cleared.

If you reopen the blend file the shape keys are properly removed.

Exact steps for others to reproduce the error

Add shape key to an object
Delete the shape key
Delete the object bpy.ops.object.delete()
bpy.data.shape_keys is empty
Add shape key to an object
Delete the mesh bpy.ops.object.delete()
bpy.data.shape_keys is not empty

@ideasman42, not sure we'll consider this a bug? That's just a weak design of shapekeys which originally were supposed to be reusable across multiple datablocks.

The shapekey is stored in the Mesh, on removing the object the mesh isn't removed either.

This is working as intended, closing.
