When the number of (static) workspaces decreases, we relocate windows from extra workspaces before removing them. As removing a non-empty workspace is not allowed, we assert that it doesn't contain any windows before removing it. However that assert is - pointless, because meta_workspace_remove() already asserts that the workspace is empty - wrong, because even empty workspaces contain windows that are set to show on all workspaces Simply drop the assert to avoid a crash when trying to remove a workspace while on-all-workspaces windows are present. https://bugzilla.gnome.org/show_bug.cgi?id=784223
