I installed libgtk-3-0 v 3.14.4-1 which removed ubuntu-desktop any some other applications. I then reinstalled the missing applications, restarted my computer and the problem with gedit was fixed but the libgtk-3-0 package was listed as broken and the package management system wouldn't let me install new software so I reverted libgtk-3-0 back to 3.12.2-0ubuntu15 and the problem with gedit is still fixed. I hope this helps with finding a solution as wouldn't recommend anyone trying what I did to fix it as I have no idea how or why it happened and I wouldn't want anyone to break their system.
