Bug#951117: libecore1: .xsession-errors eats all disk space

[sergio]

More details:

instead of fullscreening the tilix it can be closed when it's above
another fullscreen window

I'm unable to reproduce it just after session start, but after restart
it reproduces frequently.

So the sequence is:

1. restart enlightment
2. open tilix
3. put tilix above another fullscreen window or fullscreen itself
4. close it
5. repeat the sequence several times untill errors will be massively
printed into ~/.xsession-errors

I've checked this on NUC, and it's reproducable.
