korganizer doesn't show reminders when using caldav

[Luca Olivetti]

If I add a caldav calendar to korganizer, it stops showing reminders for all calendars (even local ones).
It seems to be specific to caldav, since if I enable more than one local calendar the reminders work.

I don't think it's relevant, but the server is SOGo (http://sogo.nu), version 2.3.18, and the calendar has been added with the "add calendar" wizard, selecting "dav resource" (localized,I don't know its name in English) then "ScalableOgo".
