I bet u saw with error message window “System problem detected” in Ubuntu. This issue comes from existance of files in /var/crash folder. Inspecting those files could help you to validate the errors in applications and check what's wrong with it.
It's enought for first time to delete the files in folder to get rid of the messages:
sudo rm /var/crash/*
But this variant is not permanent and error message window will be displayed if application crash again. You can delete those files every time after system boots, but there is another solution. Disable Approt (debug tool) and permanently fix this problem.
To disabple Appor edit curent file:
sudo gedit /etc/default/apport
Content of the file:
# set this to 0 to disable apport, or to 1 to enable it # you can temporarily override this with # sudo service apport start force_start=1 enabled=1
Change enabled value to zero.
But take in point it's better to fix the application to prevent it from crash.
