[Pkg-xfce-devel] Bug#884802: xfce4-panel: Undeletable buttons of nonexistent processes.

[Lorenzo Ancora]

Package: xfce4-panel
Version: 4.12.1-2
Severity: minor

Undeletable buttons of nonexistent processes.

Dear Maintainer,
on `xfce4-panel 4.12.1 (Xfce 4.12; Openbox 3.6.1)`, closing a window when the
right-click menu is open leaves a menu entry that never disappear.

* What led up to the situation?
Closing a window when the right-click menu is open on a Window Buttons panel's
application button.
* What exactly did you do (or not do) that was effective (or ineffective)?
I've opened two windows of `Thunar 1.6.11 (Xfce 4.12)` and right clicked on the
single application button that represented the two windows.
* What was the outcome of this action?
Choosing "close" from one of the sub-menus leaves a ghost entry in the menu.
Doing the same thing for all windows leaves a button with the generic app icon
and no functionality.
* What outcome did you expect instead?
The menu entry must disappear if the window was closed.
The button must not exist if it cannot represent at least a valid window.
