Bug Description

I had large number of files open (more than a dozen) and was searching through each one for test to replace. I was saving and closing each file after I had finished my editing. Then I would select the next file to work on from the top tab bar.

I had two Gedit windows open. One of them only a had a single file in it.

Both gedit windows turned grey, eventually close and then the crash report was posted.
