STR:
1. Open any application then open another window / instance of it.
2. Click the icon of the app on launcher.

Results:
1. Desktop had some blinks and remained as it was (the current window).
2. After that a crash report appeared (experienced an internal error)

Expected Results:
1. All the instances of the current app should have appeared.
2. I should have been able to choose any window.
