#### Summary:
<!-- Summarize the issue/suggestion concisely: -->
Inkscape crashes when selecting an object (in this case a group of paths) that has been copied into a file using 1.3 from a file created in 0.91
#### Steps to reproduce:
<!-- Describe what you did (step-by-step) so we can reproduce: -->
- open Inkscape
- load file that was created with 0.91
- copy group of paths from file made with in 0.91 (that was opened in version 1.3)
- paste into file in ver1.3
- (inkscape crashes)
- open inkscape again and load the emergency saved file
- try to select the copied group of paths
#### What happened?
Inkscape crashes
#### What should have happened?
the copied group of paths would be selected
Sample attachments:
the_mound is the 0.91 file, testing new stuff is the new one. (g4869 in the layers and objects is the problem group)
<!-- Attach the sample file(s) highlighting the issue, if appropriate. -->
