Comment 4 for bug 1819301

Update: Thanks to Rene's suggestion, I was able to get pcbnew to startup by removing the configuration files and having Kicad regenerate them. I've included the configuration directory as an attachment.

I was able to duplicate the issue by taking my board design, passing it to pcbnew, exporting it to a Spectra DSN file, import the Spectra file to freerouting, route the board, import the Spectra Session file, save the file, exit pcbnew. Then on restart of pcbnew from Eeschema, Kicad would hang (kicad, eeschema, pcbnew unresponsive).

I can upload the board design, if you like. It's just a teensy 3.2 board.
