title: IntelliJ IDEA lost icon after launch
body: <p>I changed to use JetBrains Toolbox App to manage IntelliJ IDEA/PyCharm/WebStorm (I have reinstalled all the JetBrains products using Toolbox App) in my Ubuntu 16.04.2 recent days. Now I have an issue: each time when I started IntelliJ IDEA from the Toolbox App or from the command line (<code>./idea.sh</code>), IntelliJ IDEA could run as I wished but without an icon in the launcher bar, only a white question mark. However, if I start it by double-click the thumbnail of it, everything would be OK, including a beautiful icon in my ubuntu launcher bar!</p>
  
  <p>Does anyone know how to fix? This is not a big trouble, but I just want to make everything fine with my develop environment.</p>
