[Gimp-user] rotate + crop -> 1 action?

[B.W.H. van Beest]

Dear GIMP people,

When I rotate an image using GIMP a few degrees, to correct that I 
didn't hold my camera horizontal, the next step is to crop the rotated 
image such that it appears upright again.
I realise that it must be possible to do the two actions all in one go, 
as  the rotation angle  fully determines the (max)  area to which the 
picture can be cropped. Is this implemented somewhere in a script, or is 
this functionality available via other means?
