I think that the problem is the combination of bash and the
gnome-terminal. While I'm in the directory '\E', I open a
gnome-terminal (by Ctrl+Shift+N). The new terminal will have the mess
up path in the prompt.

However, if I start with a directory that is not '\E' and then cd to
'\E' in the existing gnome-terminal, the path doesn't mess up.

I tried some other name '\L'. But it doesn't cause the problem. I'm
puzzled what the cause might be.
