Bug ID: 370508
Summary: SIGSEGV on plugging in external monitor
Product: plasmashell
Version: 5.8.0
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: Multi-screen support
Assignee: aleix...@kde.org
Reporter: artjom.si...@gmail.com
CC: plasma-b...@kde.org
Trying to plug in a second monitor, I get a SIGSEGV.
I installed a debug version of the qt5-declarative package in the hope that the
coredump provides at least something useful. How can I help to debug this
further?
