“Error detecting shell” when launching Gnome Tweak Tool

[greenbeaver]

Hi there.

I have a bit of a problem when opening Gnome Tweak Tool. I am logged into Gnome Classic now, but it doesn't load when logged into Ubuntu or Gnome 3 either.

When logged into Gnome 3 my resolution is huge and I can't change it in System Settings - hoping the fix might've been in Tweak Tools.

This is the code I get when I try to launch from terminal:


__

Let me know if there is any more information I can provide.

Thanks for your help...
