How can you fix this? Squeak 5.3 for AMD64 with Seaside from the installation instructions (3.4.6).

It seems that in Squeak the error handler is capturing deprecation signals? Since this is just a deprecation, it should continue to work. However, I am not using Squeak and stopped actively maintaining it. The automated builds are failing since some time.

Incidentaly, this issue is related to one of the last fixes I did specifically for Squeak. It is still open to finish but, as I said, it is just a deprecation at the moment. https://github.com/SeasideSt/Seaside/issues/1195

I see this delightful bit in the release notes for upcoming Squeak 6.0:

- #asMutator is back to preserve the well-known Smalltalk legacy and improve the backwards compatibility for projects such as Seaside. However, new code should use #asSimpleSetter instead.

So perhaps this issue can be retired...? I am very happy Squeak made that decision.
