To quickly get to the point to observe the cause, you can insert...
�� Halt if: [interruptedProcess suspendedContext receiver == nil].
into DebugSession>>stepInto: just after the send of #step.

Then when you step into Context>>stepToSendOrReturn
step once over "context := self step"
and the second time step in until you get to
�� Context>>jump:if:

which substitutes the following context��

�� Context��

sender: self "=Undefined>>DoIt"

receiver: rcvr "=1"

method: newMethod "=Object>>#mustBeBoolean"

arguments: args "=#()"

such that in RubSmalltalkEditor>>debug:receiver:in:

the condition block

�� debugSession stepIntoUntil: [:currentContext |��

currentContext method == aCompiledMethod ]

always fails, so in DebugSession>>stepIntoUntil: ��the ��#whileFalse:��never exits.

A possible fix (if a bit hacky) is...��

�� debugSession stepIntoUntil: [:currentContext |��

(currentContext method == aCompiledMethod)��

�� or: [currentContext method selector==#mustBeBoolean] ].
