Public bug reported:

I'm not 100% sure gnome-screenshot is the culprit here, since this
problem exists both in Ubuntu 14.04 and in Lubuntu 14.04 with their
respective default apps.

The problem: Whenever I select text word by word using CTRL+SHIFT + the
cursor keys, for example right in this bug report, some weird chain of
events is triggered which starts an endless loop of the screenshot
utility du jour (depending on the desktop that is running) taking
screenshots and filling up my $HOME directory.

In Ubuntu 14.04, this has the effect of the mouse cursor becoming a
crosshair and the user being able to select a region. In Lubuntu 14.04
this only takes a screenshot and puts it into $HOME. In both cases,
there are so many screenshot processe spawned that the machine becomes
unresponsive and the session has to be killed (in my last case, 607
within ten seconds).

Where are these processes spawned and why? The machine was installed
with Ubuntu 14.04 default and then `apt install lubuntu-desktop` was
used to change the desktop, both into clean user environments. I do not
have this problem at all on another Ubuntu 14.04 machine and never had
it in 12.04.

Thanks for any help!
