I need your help here. 

There is beginTransaction() and endTransaction(). 

Why end() returns transaction? It confuses as begin() does not create 
transaction? beginTransaction() does create.

Can you try to apply patch [1] and check what is happining when you find some 
time, please? I plan to write test to isolate the problem, but I'm busy these 
days with thesis.
