Ubuntu Trusty supports qt5, but the unity-panel indicator does not: tray icons are drawn on top of the close-window button. A "hide tray icon" option would offer a workaround in this case.
More generally, and separate from this bug, tray icons are bad design, especially in modern desktop environments, where combined launcher/taskbar shows that the program is running and give access to it anyway. Tray icon is invariant in Electrum and as such it has little place in a system's "indicator" or "notification area".
