Public bug reported:

We first noticed this after the migration to Qt 5.2 and using the
Reminders app: in summary, when editing a note the application becomes
unresponsive on the phone and the CPU goes to 100% on the desktop (there
it's not too noticeable).

After a chat with mzanetti, this is related to an upstream patch that
should have probably been implemented differently, and it's now reported
in the upstream tracker [1].

This will affect every app using a sorted list on the phone
