GIMP crashes at random

[Ondedieu JF]

Hardware : LENOVO G50 (Intel 64 bit CPU)

Op system :
Description: Ubuntu 18.04.4 LTS
Release: 18.04

Using GIMP 2.10 :
gimp:
  Installed: 2.10.14+om-1ubu18.04.7~ppa
  Candidate : 2.10.14+om-1ubu18.04.7~ppa
 Table of version :
 *** 2.10.14+om-1ubu18.04.7~ppa 500
        500 http://ppa.launchpad.net/otto-kesselgulasch/gimp/ubuntu bionic/main amd64 Packages
        100 /var/lib/dpkg/status
     2.8.22-1 500
        500 http://fr.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages

When working with GIMP (former 2.8) or (current 2.10) GIMP crashes at random, whatever ongoing action. Fount no correlation between action and crash.
