Bug ID: 362863
Summary: Recursion between KDE Platform Theme and
QSystemTrayIcon (when not using Plasma)
Product: plasma-integration
Version: master
Platform: Debian unstable
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: mgraess...@kde.org
Reporter: mity...@gmail.com
When StatusNotifier is not available (i.e. when not using Plasma),
KNotifications tries to fall back to Qt's implementation, however that actually
leads to infinite recursion.
See https://bugs.debian.org/807805 for the original bug report.
Reproducible: Always
Steps to Reproduce:
1. Use an environment without StatusNotifier support
2. Use KDE Platform Theme
3. Try to run Vlc (any other application that has a system tray icon should
also work)
Actual Results:
Infinite recursion that leads to stack overflow and crash
Expected Results:
No crash
