Isync failing to ical for palm z22 after upgrade to mac os x 10.5.1

Question

just upgraded my powerbook G4 to mac os x 10.5.1, now unable to successfully complete hotsync. new events on my palm DID get added to my iCal, but hotsync manager dies before completion with an error message. see below for hotsync log details.
previously had os x 10.3.x and was syncing my palm z22 with iCal, address book, etc. just fine. to make it as simple as possible, in isync i un-checked "contacts", and under "calendars" i checked "ignore palm events older than one month". in hotsync conduit settings, "isync conduit" is set as "enable isync", all other conduits are set as "do nothing".
have pored through the many threads on sync problems with 10.5.x but didn't see one with this particular symptom. any insight would be greatly appreciated.
mac: powerbook g4, os x 10.5.1
hotsync manager 3.2.1
isync 3.0 (568.0)
palm: z22 running palm OS garnet v5.4.9

Does your Leopard install DVD look like this?
If you are using a gray disc, they are model specific.
