Qt Version: 5.9.5
Frameworks Version: 5.44.0

Distribution: Ubuntu 18.04.1 LTS

-- Information about the crash:
I was watching Youtube,
then I paused the video, exited full-screen, and minimised the browser window, 
then I clicked the Application Launcher in my Latte Dock,
then I clicked on "Software Centre" (Discover),
then I searched for "safe eyes",
then the Software Centre just crashed.

If it helps, Thunderbird was also running in the background.
