Description Matt Fagnani 2020-06-26 20:17:33 UTC
Application: plasmashell (5.19.2)

Qt Version: 5.14.2
Frameworks Version: 5.71.0
Operating System: Linux 5.8.0-0.rc2.20200625git8be3a53e18e0.1.fc33.x86_64 x86_64
Windowing system: Wayland
Distribution: Fedora 33 (KDE Plasma Prerelease)

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

I was using a Fedora Rawhide KDE Plasma spin installation with Plasma 5.19.2, KF 5.71.0, Qt 5.14.2. I started Plasma on Wayland. I started Konsole 20.04.2 on Wayland. I opened Firefox Nightly 79.0a1 (2020-6-26) on Wayland. I went to youtube. I resized Firefox. I dragged and dropped a link from Firefox to Konsole. A plasmashell segmentation fault in DeclarativeMimeData::DeclarativeMimeData at /usr/src/debug/kf5-kdeclarative-5.71.0-1.fc33.x86_64/src/qmlcontrols/draganddrop/DeclarativeMimeData.cpp:55 in kf5-kdeclarative-5.71.0-1.fc33 happened. The link showed up correctly in Konsole.

- Unusual behavior I noticed:
The task manager bar disappeared from the bottom of the screen and reappeared.

I tried the same procedure a few times, but the crash didn't happen again.

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