Client sends Delete commands to server without any reason

[shinku]

Synchronization deletes some events added by server a few syncs earlier (all added in one sync). Events in calendar were not removed/chenged by user. Events are still present on device but removed from server.
This happens from time to time (1,2 times in the month), without any reason nor visible pattern.

log from synchro with delete commands

These are just sync messages. They do not help for examination.
I'd need an Android log file for more detailed analysis.
