Comment 9 for bug 237863

Same crash as #5 in inkscape rev 22598.

The crash can be avoided by commenting out
     sp_document_set_undo_sensitive (local_doc, false);
and
      sp_document_set_undo_sensitive (local_doc, saved);

in write_to_xml in the file src/ui/widget/registered-widget.h

This is probally not a good fix. I dont know what other things that are affected and those lines of codes are probably there for a reason.
