#doSemanticAnalysisIn: error

From time to time when I halt the execution (or try to halt it) I get
walkbacks reporting a MNU in
nil #doSemanticAnalaysisIn: nil

Now after hiting Alt+. for a while I was able to recover the control
of the image, but when selecting the "Morphic UI process" in the
process explorer I get a similar walkback (see screenshot).

Why is this? Is it a know bug?

is it possible that you don't have the source code of your image? Both
the .changes and .sources must be available

Well... I have all the sources and changes.
But when this happens it seems the image/vm gets in a limbo, saying
PharoV30.sources wasn't found, etc.

My error was raised by a infinite recursion involving a #halt sent
during the printOn: (which sends #javascriptOn: in this case).

This is the offending call stack that got recursive.
