Comment 2 for bug 1441261

I sort of fixed this issue with the following command:

sudo usermod -s /bin/bash <username>

Apparently the x-terminal-emulator link is looping somewhere, but pointing my default shell to bash set everything straight.

It seems that the default install of Terminator was not compatible with my environment. Uninstalling Terminator, even with --purge, did not remove everything from my machine. Vim and screen were still trying to access Terminator after it was uninstalled. I had to add a line to my .vimrc to set the Vim shell to bash, and reinstalling screen did not work. Screen is still broken after this "fix."
