It would happen together with an error: QPainter::begin: Paint device returned engine == 0 and would be caused by the size provided to QIcon::pixmap being empty, itself caused by the availableSizes list being empty for the Selected mode. This bug was most often hidden by the fact that the Selected icon mode was not triggered properly since we usually only set menuVisible after calling updateIcon, and most of the time when it did, we would overwrite it right after with a Normal mode icon. Fix the issue by disabling the broken feature completely since the default Selected icon is grayed out while tray icons are now usually black (or white when selected). To support the dark menu bar mode on 10.10 we'll need to use NSImage's setTemplate anyway and that knowing in advance if we can invert the colors ourselves would also better solve the menuVisible usecase.
