terminal-app echoes commands twice after foregrounding the process again after it was stopped

[Matthias Apitz]

If you run some processes in the terminal-app and you have to slide away this application (for example due to an incoming call), the processes get stopped; you can resume them again with the 'fg' command, but after having done so, all commands get echoed twice, for example:

phablet@ubuntu-phablet:-$
[1] Stopped ssh localhost

phablet@ubuntu-phablet:-$ fg
ssh localhost

phablet@ubuntu-phablet:-$ echo foo
echo foo
foo
phablet@ubuntu-phablet:-$

see also attached screen.

Also happens without switching to a different app:

*do an ssh

*STRG+Z (or CTRL-Z) to stop the ssh

*fg to resume

-> double printing of commands
