Comment 4 for bug 1435905

I am attaching a log.

After some trial and error, I was able to set up my terminal in a state such that I could reproduce the error in a single keystroke.

The transcript of the session is:
$ script -f /home/$USER/bin/shell_logs/$(date +"%d-%b-%y_%H-%M-%S")_shell.log
Script started, file is /home/bbeltr1/24-Mar-15_13-29-44_shell.log
$ tmux attach
[vim renders]
[I hit <ctrl-q>j, to change to the (non-existent) "next lower" tmux pane]
[the character appears in my vim status line]
[I hit <ctrl-q>d to detach]
$ Ctrl^D

I should also point out that if I resize the window before I detach, the character disappears, presumedly because vim re-renders the status line. More in general, any action which re-renders that character on the screen will cause the glitch-character to disappear.

Thank you for the quick response!
