lutris crashed with AttributeError in on_game_start(): 'NoneType' object has no attribute 'show' #57

Hi, everyone! I wanted to report a minor bug that occurs every time I launch a game from the Ubuntu launcher, which runs /usr/bin/python3 /usr/games/lutris lutris:rungameid/2. The game successfully runs, but I get Ubuntu’s “The application Lutris has closed unexpectedly” dialog with the following traceback:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/lutris/gui/widgets/sidebar.py", line 377, in on_game_start
    self.running_row.show()
AttributeError: 'NoneType' object has no attribute 'show'

Here's a snippet of the output when I run the same command from the terminal:

Let me know if there’s any more information you need. Thanks!

I think this happens when you quit lutris while the "running" section in the sidebar is selected. You can workaround this by opening lutris, selecting another category then quitting lutris. This should fix your game shortcuts while we prepare a patch for the issue.
