I can add the following:

When I run Scribus from gdb like this and try to open any of the files 
I don't get a Signal 6 error message. Instead Scribus shows the progress 
opening the file which goes to about 40% and then Scribus hangs.

I guess it is a bug in copying and pasting the frames into a new document.
