Hi Colin,

thanks.  The assertion on )LOAD was caused by the .xml file being truncated.

I have changed the )LOAD command to print a message when it detects a truncated .xml file.
I also changed the )COPY command to deal with truncated .xml files, provided that the truncation
happens late in the file (like in your case). You should now be able to )COPY the broken .xml file, SVN 503.

The root cause - the failed )SAVE - is not fixed yet. For that I would need more information such as
the printout when the )SAVE failed.

I'm getting this assertion failure on a workspace )load
I can't )copy it either
The previous )save crashed also
