I have installed the latest snapshot, and this is still happening.
Reproduce code:
---------------
I am not able to reproduce this code, this only happens on the production
server, with more than 4 million records in the database, every page I
tested does not cause this to happen, so I am now thinking that this might
be caused by specific data coming from mysql
