One thing that would help for next time would be saving all the stack 
traces (especially the first one). There used to be a preference 
#appendToErrorLog that did just that. Easy enough to add: just don't 
delete the old squeakdebug.log and do a #setToEnd before writing. As it 
stands, the stack trace we have doesn't say anything about how that text 
morph got that way. Perhaps an earlier, more significant, error was 
overwritten and that would have told us something.

Cheers,
Bob
