Description George Goodman 2017-09-07 16:07:03 UTC 
Application: plasmashell (5.10.5)

Operating System: Linux 4.10.0-33-generic x86_64
Distribution: KDE neon User Edition 5.10

-- Information about the crash:
I'd just entered my password at the display manager screen and hit return to login. When I looked back at my screen, all looked well, but for the red notification icon for a Plasma crash.

The crash does not seem to be reproducible.

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

New crash information added by DrKonqi

plasmashell (5.13.2) using Qt 5.11.0

Desktop image had just displayed after boot mostly compleated, as I moved the mouse across the center of my screen (nothing of note behind it, so likley not an issue with hover), the screens (I have 3) went black, then recovered.

There's /a/ chance this is fixed with 0aab7d23a2ce155c4beb5cf77fcac02c93b183b7 in kdeclarative that fixes uses of a QOpenGLShaderProgram, which is where this bug is.
