I tried to delete the files that you said.
The result is identical, Rosegarden closes anyway.
On "open" button click the message on command line is:
------------------
[FileDialog] FileDialog::FileDialog(...)
     using paths:  examples:  "/usr/share/rosegarden/examples"
                  templates:  "/usr/share/rosegarden/templates"
                 rosegarden:  "/home/renedrive/rosegarden"

libpng warning: iCCP: known incorrect sRGB profile

The first thing I'd do is close Rosegarden, delete

  ~/.config/rosegardenmusic/Rosegarden.conf

Then I'd start over, and see if that made the problem go away.
