Hi noetus,

there was another user which had some problems with
nuevasync and google calendar, but I can not remember
if it was solved.

I think I need the full event data to reproduce this error.
Can you please export the event data of this event
with sqlite3 (sqlite3 is a commandline program, which can read and
edit your event database):
open x-term and do the following commands:
sqlite3 /home/user/.calendar/calendardb
select * from components where summary ="EVENTTITEL";
.quit

(where EVENTTITEL is your event title)

And paste the output here (or send me PM).

Nicolai
