Application: plasmashell (5.11.5)

Qt Version: 5.10.0
Frameworks Version: 5.41.0
Operating System: Linux 4.14.13-1-MANJARO x86_64
Distribution: "Manjaro Linux"

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

I had konsole, firefox, and qbittorrent all minimized.  I clicked konsole's button on the panel taskbar to unminimize it.  

- Unusual behavior I noticed:

Instead of unminimizing konsole, it acted like I was trying to drag konsole's button.  After clicking it a few more times, konsole became unminimized, but plasmashell crashed.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
