How do I disable Shutter plugins?
The initialization of plugins should only appear once (e.g. after updating Shutter or a fresh install of Ubuntu). If this dialogue appears every time you start Shutter it is simply a bug. There is an updated version of Shutter in our PPA. Please give it a try to see if it is fixed.
sudo add-apt-repository ppa:shutter/ppa
sudo apt-get update && sudo apt-get install shutter
