The first sync succeed, the second one (and the next ones) fails.

version: vdirsyncer, version 0.3.1

config:

[general]
status_path = ~/.vdirsyncer/status/

[pair my_calendars_home ]
a = my_calendars_home_local
b = my_calendars_home_remote

[storage my_calendars_home_local]
type = filesystem
path = ~/.calendars/home
fileext = .ics

[storage my_calendars_home_remote]
type = caldav
url = http://dav.myserver.com:5232/user/my_calendar/home

running "vdirsyncer -v debug sync" returns:

Ugh, please update to the latest version of Radicale. I can fix this particular bug, but especially old versions of Radicale are full of bugs and I don't recommend using them.

You can try the development version of vdirsyncer with

pip install --user --force-reinstall git+https://github.com/untitaker/vdirsyncer.git

Thanks :-). The problem changed, but is still there: the first sync is ok. The second one now fails with:

error: my_calendars_home : Storage "my_calendars_home_remote" was completely emptied. Use "--force-delete my_calendars_home " to synchronize that emptyness to the other side, or delete the status by yourself to restore the items from the non-empty side.
