I’ve had this problem sporadically with iTerm on my Mac, and I seem to remember this happening recently on my Linux machines as well. If you have this problem, try this:
$ export TERM=linux
If this works, on a Mac you can set it in your .profile:
if [ "${TERM_PROGRAM}" == "iTerm.app" ]
then
export TERM=linux
fi
On Linux, you can do the same, but leave out the if and just do the export line.
