[SyncEvolution] How to read the log file

Hi, I synchronised Evolution with my Nokia E50 several times successfully. Now, I got a synchronisation error. How should I read the log file to find out 1. What calendar item caused the error? 2. How can I fix the error? In the following, I give snippet of the log file with the beginning of the error (at the bottom) and description of the outgoing message (at the top): –[2010-11-10 18:03:20.793] 'issue' - issuing command, Cmd=Replace [--][++] [->end] [->enclosing] * [2010-11-10 18:03:20.793] Item remoteID='1061', localID='', datasize=538 * [2010-11-10 18:03:20.793] Replace: issued as (outgoing MsgID=2, CmdID=9), now queueing for status * [2010-11-10 18:03:20.793] Outgoing Message size is now 1084 bytes –[2010-11-10 18:03:20.793] End of 'issue' [->top] [->enclosing] ... –[2010-11-10 18:03:22.291] 'processStatus' - Processing incoming Status [--][++] [->end] [->enclosing] * [2010-11-10 18:03:22.291] Started processing Command 'Status' (incoming MsgID=3, CmdID=3) * [2010-11-10 18:03:22.291] WARNING: RECEIVED NON-OK STATUS 500 for command 'Replace' (outgoing MsgID=2, CmdID=9) * [2010-11-10 18:03:22.291] - TargetRef (remoteID) = '1061' * [2010-11-10 18:03:22.292] Found matching command 'Replace' for Status * [2010-11-10 18:03:22.292] Status: General error 500 (original op was wants-replace) -> marking item for resend in next session * [2010-11-10 18:03:22.292] Deleted command 'Replace' (outgoing MsgID=2, CmdID=9) * [2010-11-10 18:03:22.292] Deleted command 'Status' (incoming MsgID=3, CmdID=3) –[2010-11-10 18:03:22.292] End of 'processStatus' [->top] [->enclosing] Thanks for your help, Simon
