Reminder is not saved when added to OrganizerItem

I am using Organizer API from qt-mobility. At first I was using QML Organizer
API and suspected that problem is in QML but after code inspection I have
concluded that QML part is written correctly.

After that I have added C++ level function to my code and reminder was still
not available. My code was copy-pasted from
http://qt.gitorious.org/qt-mobility/contacts/blobs/master/plugins/organizer/maemo5/tsrc/tst_maemo5om/tst_maemo5om.cpp
tst_Maemo5Om::testReminders function.

As well later I have tried to use
http://qt.gitorious.org/qt-mobility/contacts/trees/master/examples/calendardemo
application. This application allows creating event and edit it after that.
Create event using this application, add alarm and save. Then try to edit this
new event and you will see that reminder is not set.

P.S. I'm not sure how to report this but bugreports.qt.nokia.com sign-up
process is broken for Chrome/Chromium browser.
