After closing lttv-gui, will get error prompt: Failed in launching local application: lttv-gui Exit value: 139
This is an upstream bug which resides in lttv. It is trigged when the user exits the lttv-gui through the menu file->exit, an segmentation fault is reported and causes the failure. When the user exits the lttv-gui by directly closing the main window, the problem seems gone.
