Bug ID: 411835
Summary: Dolphin crash when showing, hiding and showing again a
video element
Product: dolphin
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: meve...@gmail.com
CC: elvis.angelac...@kde.org
Target Milestone: ---
Application: dolphin (19.11.70)
(Compiled from sources)
Qt Version: 5.12.2
Frameworks Version: 5.62.0
Operating System: Linux 5.0.0-27-generic x86_64
Distribution: Ubuntu 19.04
-- Information about the crash:
- What I was doing when the application crashed:
1. Hover the mouse over a video : the video playback starts
2. Hover over a none video file : the video is stopped and replaced with a
preview
3. The crash happens when hovering over the video file again
- Custom settings of the application:
auto play on hover video hovering in Dolphin
Dolphin internally shows, then hide then shows again a QVideoWidget.
Could be a QtWayland bug.
X is not affected.
KDE Plasma Version: 5.16.80
KDE Frameworks Version: 5.62.0
Qt Version: 5.12.2
The crash can be reproduced every time.
-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
