Gilles this is code I wrote so I feel responsible ;-)
I have also had this crash sometimes but not reproducibly.
Is this related to the commit from toma from Monday?
That would make sense for me: If scanlib calls kapp->processEvents() it will 
sometimes process the deleteLater() event, so your patch would solve this - 
but, we may only call deleteLater if isBusy() is false, your patch calls it 
in any case.

It seems ScanLib is written with the initial scan in mind, so if it is called 
from the running UI, as from CameraUI, it is another solution to disable 
lines 337 and 338 in this case (not in the normal case) and set a busy 
cursor.

The second crash reported by Duncan looks like something I got when I tried to 
stop a KProcess not from the main thread (then I understood that KProcess is 
heavily non-reentrant).
