Comment 2 for bug 876415

The icon not appearing in the launcher seems to be a related issue, not a separate one. On my system, if I use the global menu extension, the menu bar, title, window buttons and launcher icon all fail to appear. The absence of the menu bar effectively makes the application unusable. If I remove the global menu extension, the menu bar appears beneath the panel because the global menu functionality isn't there, but the title, window buttons and launcher icon fail appear. A screenshot showing this is attached.
