We have also seen this in the Dillo downloads GUI which does something
similar but deletes the widgets from a timeout callback, so it's not
exclusive to code that deletes a widget from its own callback.
Strangely, that version of the bug is harder to replicate: I couldn't
reproduce it at all but other developers saw the same problem that my
toy example demonstrated and the same fix worked for them.
