ISync w/ T637, SyncServices assertion failure - suggestions?

Question

I haven't used my phone (Sony Ericsson T637) for syncing with my Mac in a while, but I've run across unpleasant errors that are preventing me from syncing the phone with the Mac. The errors associated are provided below.
2007-07-05 13:13:23.468 iSync[1641] SyncServices assertion failure (nil != entityName) in [ISyncConjunctionFilter shouldApplyRecord:withRecordIdentifier:], /SourceCache/SyncServices2/SyncServices2-194/SyncServices/ISyncFilter.m:125 the record CalendarsAndTodos:00000B0B0000 should have an entity name, but instead it is {}

Based on the message, it looks like iCal is at fault, but iCal isn't throwing errors about empty entity names. Have you all run across this issue before? Perhaps I should take this question up with the people in the iCal support forum?
Thanks in advance!
