Bug ID: 389933
Summary: Dolphin crashes when trying to drag any element
Product: dolphin
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: lorenzo.ra...@yandex.com
CC: elvis.angelac...@kde.org
Target Milestone: ---
Application: dolphin (17.12.2)
Qt Version: 5.9.3
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-32-generic x86_64
Distribution: KDE neon Developer Edition
-- Information about the crash:
I'm trying to use Wayland as much as possible so it's about two weeks i use it
as my daily driver; since the latest update (Plasma 5.12 - 5/2/2018), Dolphin
started force-closing everytime i try to drag and drop any element. To be
precise, it crashes in the exact moment i move the cursor: i can easily double
click or long click a folder, for instance, with no issues, till the second i
move the cursor (both with physical button click and double touch).
The crash can be reproduced every time.
-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
