Many files that I created in Inkscape 0.48.5 now do not open in 0.91; there is no visible evidence that 0.91 even launches, and it doesn't show up in task manager, so no error message is returned. Files created in 0.91 can still be opened in 0.91, and likewise files created in 0.48 can be opened in 0.48.
One such file is attached.
