Before loading, try first disabling the Iceberg Metacello integration in the system settings.

I believe this can also be done by evaluating:

Iceberg enableMetacelloIntegration: false.

Also, if you are on windows, do not load the master branch but load the tonel branch of Seaside.

So:

Iceberg enableMetacelloIntegration: false.

Metacello new
 baseline:'Seaside3';
 repository: 'github://SeasideSt/Seaside:tonel/repository';
 load

Although the Iceberg integration works just fine for me, I do recall issues with crashing images similarly in the past.

Let us know what happens..

Cheers

Johan
