Christoph Thiede uploaded a new version of Tools to project The Trunk:
http://source.squeak.org/trunk/Tools-ct.1122.mcz

==================== Summary ====================

Name: Tools-ct.1122
Author: ct
Time: 31 January 2022, 12:09:47.193979 am
UUID: a16ebf6e-8c03-a644-a2d8-1165ac1ef7ff
Ancestors: Tools-mt.1121

Protects the debugger against evaluating a symbol label as a selector on the model.

Formerly, the following would break your project with a recursive error:

	[] newProcess debugWithTitle: #myDebugger full: false

Thanks to Marcel for the help!
