Hm, and this is just something that happens on shutting down the application. 
A singleton gets destructed and deletes the plugins it had loaded.

I actually haven't seen the crash myself, I only have what the bug reporters 
reported -- that downgrading sip and rebuilding Krita made the crash go away 
for them. That must mean they have rebuilt Krita's bindings, too.
