My apologies for not noticing this sooner.

Since build #175,
http://build.squeak.org/job/SqueakTrunk/178/testReport/ToolBuilder.MVC/MVCToolBuilderTests/testButtonFiresSymbol/
shows a failure, saying

Error Message

PS At some stage we ought to think of getting CI to report
regressions. However, we really ought to have a clean green test suite
before that, or we'll be spammed every time the build runs. When I'm
hacking on the CI scripts, that can be quite a lot!
