That doesn't sound right. Anything that connects to say 
`ScintillaObject::key-press-event` has the opportunity to propagate that 
signal to other handlers by returning `FALSE` from the handler function. 
Any plugins which swallow GTK+ events, preventing them to be handled by 
other plugins or core itself, should be highly suspect, as far I can see.
