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

I was seeing weird behavior, where I'd try to start shutter and I'd get a screen saying, Updating upload plugin information. And that screen would just sit there for 1-2 minutes.

Trying to start shutter from the commandline, it was outputting messages about /usr/share/shutter/resources/system/upload_plugins/upload/vgyme.pm

So I tried simply getting rid of that upload directory (moving it to a backup location, just in case):

sudo mv /usr/share/shutter/resources/system/upload_plugins/upload ~/backup_upload

I then rebooted (which I think was the core of my problems), and now starting shutter works just fine. So whether they were the problem or not, I think I'll happily leave those plugins out.
