Comment 78 for bug 60448

For the record, I'm having this problem, even if my file won't go too big to crash my system, because I logout everyday.

I'm using 16.04 (LTS) with 'lightdm' and 'awesome' window manager, so no gdm here.

For me, it seems it's firefox plugin container of adobe's flashplayer which is dropping tons af Gtk errors inside that file (but flash works nicely) (we're talking something like 1 megabyte per minute).

Anyway, I tried to do some dirty logrotate, but it doesn't work. Even 'copytruncate' won't do the job (copy works but not the truncate part...). So if anyone ends up here, don't try that.
