I believe this problem is already indirectly solved on the master
branch, since we now visit the file before creating the frame.  What I
see here with the master branch code is an error message saying
"*ERROR*: File is not readable: FILE", and the client exits without
leaving the terminal in a messed-up state.

Would it be possible for you to try the master branch and see if it
indeed solves the problem?

Thanks.
