Thank you very much for your debugging effort.

After learning about TUI, I thought disabling this feature
based on the terminal capability would be one way to handle this issue.
So your patch would be very much appreciated.

Still being puzzled why I didn't realize this TUI feature for such a
long time. It is not clear when TUI is enabled in Debian Package.
It is possible it was not enabled even in the current release and only
enabled in Jessie (experimental and the would be mainline release in the
next release cycle).

Thank you again.
