The system.log says (don't know if it's related; there are sevral passages like this one):

I have two users on my machine (iMac G5, iSight, Mac OS 10.5.8). Same problem with both users. I have tried to delete all mail-related files in the library (e.g. Mail folder and

I have also repaired permissions and installed the combo update of 10.5.8.

Before I started the for the first time, I migrated programs and one user profile from another mac (MacBook Pro running Snow Leopard). I guess this might have caused the problem.

I don't have a Leopard system disc (the OS was installed on the hard drive when I had to have it (the hard drive) replaced by an official Apple shop. I don't know what more to try...

Migrating from Snow Leopard may well be your problem. Snow Leopard only runs on Intel machines and the majority of it's applications and frameworks are not "universal" binaries.

Most likely, the Snow Leopard apps you migrated across to Leopard were built with Snow Leopard-specific features only and can't be run on any OS version before Snow Leopard.

The update_dyld_shared_cache errors you've got might be caused by the migration of some programs from Snow Leopard. If you boot into safe mode this dynamic library cache gets deleted and might solve your problem. Basically - hold down 'shift' when the grey screen with the Apple logo appears at boot.

Check out and the links from there to learn about safe mode.

Which programs did you migrate? Because you may have some Intel-only binaries on your G5 now I don't know what other problems lie in store.
