Hi,
I am (was) quite happy with davdroid and radicale, until suddenly all my devices start to fail syncing the calendar (contacts are fine). Below is a logcat and the corresponding VTODO snippet in the calendar file (at least I believe this is it, because that is the file name that was mentioned last in the catlog…

P.S. Update: I am not sure if it was the update to the latest davdroid, a change in configuration of the radicale server, or a change in the calendar data. I deleted the specific VTODO, but it stopped and died at another VTODO (which had not been changed for a long time), so I do not think it is the calendar data that is at fault.
P.P.S. THis is with 0.5.8a, I will test 0.5.8.1 as soon as it is on fdroid.org
