David Edmundson c215c54ece Avoid potential disconnect of all signals in IconItem 
Summary:
m_svgIcon can be null.

disconnect(q, nullptr, nullptr, nullptr); would have pretty catastrophic
consequences as it disconnects everything. Anyone listening for
QObject::destroyed of IconItem for cleanup would no longer get anything.
That could lead to obscure conditions.

ShaderEffectSource watches for the source being destroyed for cleanup
and we have a newly introduced crash with ShaderEffectSource that seems
to come from this patch.

BUG: 421170

Test Plan:
Someone who could reproduce the crash reliably confirms it fixes the
issue

Plasma Framework

Foundational libraries, components, and tools of the Plasma workspaces

Introduction

The plasma framework provides the following:

  • QML components
  • A C++ library: libplasma
  • Script engines

QML components

org.kde.plasma.core

Bindings for libplasma functionality, such as DataEngine and FrameSvg, see @ref core.

org.kde.plasma.components

Graphical components for common items such as buttons, lineedits, tabbars and so on. Compatible subset of the MeeGo components used on the N9, see @ref plasmacomponents.

org.kde.plasma.extras

Extra graphical components that extend org.kde.plasma.components but are not in the standard api, see @ref plasmaextracomponents.

org.kde.plasma.plasmoid

Attached properties for manipulating the current applet or containment, see @ref libplasmaquick

libplasma

This C++ library provides:

  • rendering of SVG themes
  • loading of files from a certain filesystem structure: packages
  • data access through data engines
  • loading of the plugin structure of the workspace: containments and applets

See @ref libplasma.

Script engines

Provides support to create applets or containments in various scripting languages.
