PPC PowerMac kernel panic - anyone else have this issue?

Hi

Just reg'd - Older mac (PPC G5 dual core), SAV 7.2.4C

had 2 kernel panics which _may_ be related to this release in that the last entry in /var/log/system.log was the same on both occaisions

SophosAntiVirus[71]: exception raised in delegate's message handler: *** -[NSCFDictionary setObject:forKey:]: attempt to insert nil value (key: OriginalFilePath)

Just wondering if anyone else is seeing these errors but _not_ having kernel panics - you know the types - walk in to the room and hear the fans going full blast and it needs the power button held in ... usually recovers fine as the OSX filesystem is robust.

Cheers

Neil
