Bug Description
Before my update to Ubuntu 18.04 I was using Octave under 16.04. I am not a frequent Octave user (once every few months). I updated to 18.04 a couple of months ago and tried running octave today only to find that it would not start from my command line. Instead, I see:
$ octave
octave exited with signal 6
A quick internet search suggested a couple of options but nothing that is obviously this problem. Filing an Ubuntu bug as it happened on Ubuntu and it might have been brought about by the upgrade between LTS releases.
+bug 1156575 was suggested as a possible duplicate but that is quite old and not what I think I am seeing.
Somewhere on a search result, it was suggested I run an strace with octave. I have attached the output of `$ strace octave > ~/octave-strace.log 2>&1` as octave-strace.log

Further diagnostic suggestions were to try:
$ octave --norc
octave exited with signal 6
$ octave --no-gui-libs
GNU Octave, version 4.2.2
$ octave-cli
GNU Octave, version 4.2.2
So the problem seems to be related to the GUI libraries for me. I am not much help at diagnosing more than that. I am happy to try running any commands people thing would help lead to a diagnosis. The problem seems to be very repeatable for me at present.
