[Pharo-project] invalid utf8 input detected

May 17, 2009

      Hi,

Recently I encounter a strange error:
- I sometimes get a debugger due to some problems in my code
- when I try to investigate the trace, I get another debugger saying  
that "Invalid utf8 input detected'"

This second debugger I can investigate, the previous not. It looks  
like something got messed up with the text conversion of the sources.

I am working on 10306 using the 4.1.1b2 VM on Mac. The code I am  
working on is loaded from squeaksource (Moose, Glamour, Mondrian).

Anyone can confirm this problem?

Cheers,
Doru
