Comment 5 for bug 533548

Looks like we have a whole lot of bug reports on this topic, all using Rhythmbox as an example but focusing on indicator-applet's bizarre behaviour. The trouble is that they have very different descriptions, which could cause issues in keeping track of the specific problem. I think it's justified to call this the exact same issue as the icon alignment thing, since doing menus the right way will resolve the checkbox problem magically (since GTK+ is, in fact, very magical when treated correctly).

Bug #519804 is the oldest of the bunch that I can see, so I'm marking this as a duplicate :)
