Bug#987066: xfce4-panel: Crashes when removing a launcher
Package: xfce4-panel
Version: 4.16.2-1
Severity: important
X-Debbugs-Cc: jvalleroy@mailbox.org
Dear Maintainer,
* What led up to the situation?
I removed a launcher. I tried this 3 times, with 3 different
launchers, and had the same result.
* What exactly did you do (or not do) that was effective (or ineffective)?
I right-clicked on a launcher in a panel, and clicked remove.
* What was the outcome of this action?
All the panels disappear. After logging out and logging in again, I
can see that the launcher has been removed.
* What outcome did you expect instead?
The launcher should be removed without all the panels disappearing.
I took a log with PANEL_DEBUG=1, so I will attach that to this report.
