crash after deleting list

It seems to be that the reference count may be bad, like, objects using GtdTaskList reference while they don't hold real reference to it.

I've spent more time than I was willing in order to track this... did not find the root cause.

Code is git master, very easy to reproduce:
1-) Create a list (local)
2-) Delete it
3-) Crash

Backtrace attached.
