-- 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
