Link to original bug (#106518)

Description

Starting weston under valgrind, opening a terminal, calling evolution, terminating evolution, typing 'exit' in the terminal, closing the terminal with the 'X' symbol, leaving weston prints the text below.

Why isn't the terminal closed, when I type 'exit'?
