PC Editor, crash

[Riccardo Mottola]

Hi,

ProjectCenter Editor qas reasonably stable that I used it and edited 
small project without hiccups. Lately I have noted it crashing, I was 
unable to find core files, I was able right now to get it crash in GDB.

reported exception - <NSException: 0x2b427348> 
NAME:NSInvalidArgumentException REASON:aString object passed to 
-[GSAttributedString initWithString:attributes:] is nil INFO:(null)

I get:

The first thing I checked is for recent changes in ProjectCenter 
PCEditorView and I don't see anything recent change that could affect this.

PCEditorView is just calling super. All other methods are standard GUI 
methods. Why should they generate and/or bark about nil?
Is it correct that nil is not accepted as argument for insertText? I 
could add a check for nil and not propagate to the super class in htat 
case, but isn't that just a workaround?
