Chat crashes with OS 10.5.8 on G4 Mac's

Question

I do not know if this is a known issue, but here is what I am struggling with.
Hardware
G4 Tower or Cube
OS
10.5.8 with 1.5GB or RAM
*Web Camera*
External iSight camera (FW400) or Logitech QuickCam Vision Pro (USB)
Issue
iChat is launched. Then, when Video Preview is selected, iChat crashes with a spinning beachball of death.
Analysis
Both G4 Tower and Cube have no issue with iChat recognizing and working with eiher the external iSight camera or the QuickCam Vision Pro if +OS 10.4.11+ is used.
I am certainly aware that OS 10.5.8 is not officially supported on the G4 Tower or Cube. But, it is really odd that I cannot make the video work in iChat with OS 10.5.8 on either hardware platform.
Any assistance would be appreciated to make iChat work with video along OS 10.5.8 on the G4 Tower or Cube.

Answer 1

Hi,
I have the G4 tower listed in the specs below.
I am running 10.5.8 and therefore iChat 4.0.8
I don't have either of the cameras you list but have used a DV Converter (Firewire) before and currently have an Added USB 2.0 Cards with a UVC compliant camera from advent connected.
If you open System Profiler (Apple icon Menu > Hold the ALT key and click the first item) and go to Hardware > Firewire, what Firmware version does the iSight show up with ? (1.0.3 is the last/latest)
Is the Logitech device a UVC compliant camera ?
DO you have USB 2.0 ports ?
When you say "Crashes" do you mean you get the spinning Beach ball then it "Unexpectedly Quit" ?
If it did then can you look in your Home Folder/Library/Logs/Crash Reporter and look at the last iChat log.
Can you post that here ?
In 10.4.11 do you have any Add-ons for iChat ?
Did you transfer any of these to the Leopard Update ?
If you used iUSBCam it may need updating for Leopard.
MoreiChatEffects may be causing you an issue.
If there was a Perian, System Preference item, that enables Quicktime to play certain files (AVIs and DivX mainly) it may also need updating.
I would try to open the Video Menu > Video Effects item and check it is selected on the middle "Normal" view selection.
You should be able to do this without using the Preview.
What happens if you go to the iChat Preferences and the Audio/Video Section ?
