Version: (using KDE 4.2.0) Installed from: Ubuntu Packages Simple put: - when ark or another application that created a dialog in notification system (not all of them, some seems to be crash aware) crashes, the dialog is left int he notification forever and can't be closed or stopped. Having all apps developers to include code to remove notifications seems to be not smart and non-optimized, that's why I have a suggestion: - when kcrash (the application crashed dialog) is called, it could emit a signal to plasma/notification and tell the app is gone. If the pid is in the list of notifications, simply remove it, or at minimum, allow the user to close it.
