constant finder crashes

Have recently installed 10.4 on g4 powerpc (digital audio) and am experiencing finder crashes on regular 60-90 second intervals. I have read other threads on this subject, but none of these solutions have worked. I never even had Stuffit 11. If it gives anyone a clue, here is my redundant crash log;
