Half of this bug is the duplicate of https://bugs.launchpad.net/bugs/1754885
and NOT of https://bugs.launchpad.net/bugs/1552577 SINCE in 1552577 and 1754885
the situations what caus the problems are different, only the resulting signal
is the same.
The other half of this bug is the duplicate of
https://bugs.launchpad.net/bugs/1754887
During the creation of this error report it was not clear, which report
of the three parallel reports remained alive. But later experiments
made me clear the situation, and therefore later I allowed the apport-
gtk produce the SEPARATE much more precise reports 1754885 and 1754887.

Title:
either apport-gtk crashed with SIGSEGV or x-server crashed because of
xzgv magnifying
Status in apport package in Ubuntu:
New
Bug description:
It happens time to time, when I try to magnify a scanned text-picture
in XZGV, suddenly the whole graphical session terminates, I see the
monitor in framebuffer character mode, and then I can log in for an
other graphical session. Usually I reboot just after this login, and
after this reboot I get the crash report possibility, ... this time
three in parallel, but only the "apport-gtk crashed with SIGSEGV" out
of these was successful to submit a crash report.
This is the reason why the summary is a bit unsure: "either apport-gtk
crashed with SIGSEGV or x-server crashed because of xzgv magnifying".
I am not sure whether there is any problem with apport-gtk, because it
might happen, that only the reboot disturbed it (I make the reboots
before any crash report opportunity window shows up).
I think the real problem is, that magnifying a larger picture in XZGV
can kill the graphical session, regadless what other jobs wanted to
remain alive in it.
(this is 18.04 development branch, and xzgv 0.9.1-4, everything
(evrypackage) are fresh up to date)
