[pkg-cinnamon] Bug#766819: Something to try to make the issue go away

[Margarita Manterola]

Hi Christoph,

I recently came across a machine that was experiencing a 
very very similar issue as the one you described. This was
running Ubuntu Trusty, so no systemd involved at all.

It turned out that what was happening was that every time
a file was opened or closed, the recently-used.xbel file was
read by cinnamon and for some reason that caused cinnamon
to freeze. Unfortunately, I didn't keep a copy of the offending
recently-used.xbel file, so it's hard to know WHAT is there that
is causing this.

The next time this happens to you, please do the following:
$ mkdir -p ~/.config/gtk-3.0
$ echo -e "[Settings]\ngtk-recent-files-max-age=0\ngtk-recent-files-limit=0" > ~/.config/gtk-3.0/settings.ini
$ cp ~/.local/share/recently-used.xbel /tmp/
$ rm ~/.local/share/recently-used.xbel

Then log out and log in.  If this gets rid of the symptom, 
then we know it's the same problem.  If that's the case, 
please look at the copied file and check if there's anything
private there and if there's not, attach it to the bug so that
we can try to figure out what recently used things can 
cause this.

Thanks!
Marga
