Starting Xfce4 with `GDK_SCALE=2 GDK_DPI_SCALE=1`, the workspace switcher flickers over the time in the menu. Removing the plugin, the panel crashes with the trace below.

Comment 1 Simon Steinbeiss editbugs 2018-05-26 00:34:28 CEST
I think this is a duplicate of https://bugzilla.xfce.org/show_bug.cgi?id=14144

Thanks for the backtrace though
Comment 2 Simon Steinbeiss editbugs 2018-05-29 00:13:05 CEST
Closing as duplicate.

Comment 3 Simon Steinbeiss editbugs 2018-05-29 01:09:47 CEST
@Paul: Could you try the patch attached to the original bugreport? Thanks!
Comment 4 Paul Menzel 2018-05-29 11:24:45 CEST
No idea, where to reply, but testing [1] from bug 14144, it still crashes, adding the workspace switcher and removing it to the horizontal top panel with everything scaled 2x on a 4K HiDPI Dell display.

```

Comment 5 Simon Steinbeiss editbugs 2018-06-05 01:06:50 CEST
Reopening: As the other bug seems to be actually resolved for the reporter with that patch I presume this is a different bug.
Comment 6 Andre Miranda editbugs 2018-09-15 18:47:39 CEST
@Simon, the panel is crashing again on me when removing workspace switcher, at the same spot reported here (xfce-panel-plugin.c:922). I have no idea why it worked before and now is crashing again. I tried to build panel at that commit (d614f388b0202ae55377b1058d90381b226f4deb), still crashing. Sorry for the false negative =/
Comment 7 Simon Steinbeiss editbugs 2018-11-19 20:25:42 CET
@Andre: Strange, I can't reproduce anymore, so here the issue is quite definitely fixed...
Comment 8 Andre Miranda editbugs 2018-11-20 00:38:32 CET
As commented in #xfce-dev, yes it is still crashing with current git master (805249296df27e1af44398e1c4f365442eb49616), at the same line. The point is: since this is a failing assertion, in order to it crash, panel should be configured with debug enabled.

@Simon, I'm far from gtk expert, but that part of code doesn't make much sense to me:

  if (plugin->priv->menu != NULL)
    {
      /* remove custom items before they get destroyed */
      for (li = plugin->priv->menu_items; li != NULL; li = li->next)
        gtk_container_remove (GTK_CONTAINER (plugin->priv->menu), GTK_WIDGET (li->data));
      /* attached menu is destroyed by GtkWidget */
      panel_assert (plugin->priv->menu_items == NULL);
    }

if menu_items is NULL, ok the for loop will be skipped and the assertion will be satisfied.
On the other hand, if menu_items is not NULL the for loop will remove each menu item, but they are not remove from the list, at least not explicitly.
Even if the items get removed, shouldn't we call g_slist_free (or g_slist_free_full in the for loop)?

I took another swing at this after being able to reproduce the bug (with enable-debug=yes).
Removing the menuitem from the container doesn't really destroy it and g_slist_free only frees the memory of the list, but again, doesn't actually destroy the menuitem.

So I resorted to g_object_unref which seems to do the trick. Cleaning up the GSList (as you suggested) is probably a good idea anyway, so I kept that part too.

Please test and if you can confirm the fix too set the bugreport to fixed.

Thanks Simon for taking a look, now the panel doesn't crash yay!

However some messages are emitted when workspace switcher is removed, not sure though it's related to your commit:

Yes, I also noticed those warnings. Not sure if that's directly related, but I'll try to dig into it. Most importantly the crash is fixed...
