Hello!
I'm not exactly sure how I got my server data into such a state, but I
ended up with entries in my local to remote ID map which only had a
local ID.
As a result, the server sends these items to the peer and then tries to
update the map. It does that with insertMapItem():
#6 0x00000000006163f9 in SyncEvolution_InsertMapItem
(aContext=0x15b2210, mID=0x7fff4e576bf0)

My implementation of that call faithfully checks whether the item
already exists and if so, refuses to update it, as specified in
sync_dbapi.h. The result is a failure to save the admin data. This error
is not returned to the client and the next sync is again a two-way sync
where the same problem occurs once more.
/*! Map table handling: Insert a map item of this context
*
* @param <aContext> The datastore context
* @param <mID> MapID ( with \<localID>,\<remoteID>, <flags> and
\<ident> ).
* A new item with <localID> will be added.
*
* @return error code, if this MapID can't be inserted, or if already existing
*

*/
_ENTRY_ TSyError InsertMapItem( CContext aContext, cMapID mID );
Should my implementation treat attempts to insert an item which already
exists as an update? TAdminData::InsertMapItem() seems to do that.
