Sure..
But it didn't help. I am almost sure it is a CFRetain(NULL) problem,
but.. It's not in my code.
I think the key is to know what is generated in
_NSKeyValueObservationInfoCreateByRemoving. I think it use some data
generated in my code, possibly some data being NULL, that should not
be NULL.
Best regards,
Vincent

I'd like to know witch kind of problem could cause this issue.
Anybody have an idea?
I have tried to enable NSZombie, but it didn't help.
NSZombieEnabled does not catch problems with toll free bridged
classes,
for that you need CFZombieLevel. Since there is a CFRetain
involved it
may help you. See:
