@consindo I figured out the reason behind this bug. If you look at the AboutLightreadDialog.ui file, it looks for the icon at /media/Lightread.png. However if you look at the directory where Lightread is installed, the Lightread.png file has been moved to share/icons/hicolor/128x128/apps folder. And this is because of the setup.py file where you instruct this to be done.

Change that and this should be fixed.
