Application: plasma-discover (5.13.0)

Qt Version: 5.11.0
Frameworks Version: 5.48.0
Operating System: Linux 4.13.0-45-generic x86_64
Distribution: KDE neon Developer Edition

-- Information about the crash:
- What I was doing when the application crashed:

Looking for a VNC viewer to install. I selected one, used the back-button on my mouse to return to results. The results had disappeared, and I attempted to search again for the term "vnc", upon hitting enter (or unrelated but simultaneous) the software center crashed. 

In the background I had two Firefox windows, two and seven tabs respectively, Slack running (installed from Snap), Spotify running (also from snap), VS Code Insiders (from a deb), and two Konsole windows, one running my work development environment through docker (about six containers). In addition, running KDE connect connected to my phone. I doubt the other applications had any direct conflict with the Software Center, but perhaps there is a shared resource at a library level somewhere amongst these and the Software Center that just had an untimely race condition.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
