Hi Yoshiki,

Recently this error showed up once more and I was able to save the whole 
image. You can download image and changes at

<http://signalbscw.tcs.informatik.uni-muenchen.de/pub/bscw.cgi/0/211329>

The project is called 'patricks stern am besten'. As far as I figured out, 
the script causing the problem is 'tropfen>>a'. Possible issues may be 
a player used within the script that got deleted, or a variable of 
'tropfen' having had the same name, maybe a unicode-issue with German 
umlauts?

Attached is the SqueakDebug.log when I start the image, open a viewer for 
'tropfen' and try to open a script-editor for the Script 'tropfen>>a' by 
dragging the tile from the viewer into the world. After that I left squeak
(all on ubuntu hardy).
