right-click at the icon you're clicking to start your application, select properties. then go at the tab saying launcher. copy the command at the command box. then open the terminal (if you're using ubuntu, hit alt+f2 and write gnome-terminal . its the equivalent of winkey+r in windows) and paste it at the terminal. your program should start up (dont close your terminal). use your program until the misbehavior occurs, copy whatever has been posted in the terminal and post it here
