 Replying to [comment:24 brushtyler]:
 > I discovered another piece, it's caused by an invalid extra-call. If I
 add debug messages both before (!QgsVectorLayer.cpp:1039) and after
 (!QgsVectorLayer.cpp:1055) the qapp->processEvent() call I notice that
 there are N pre-call messages and N+1 post-call messages.
 Found, no extra-call (would be very strange!), but it's a race condition,
 see the attachment.
