Hi Reginald,

I hope you have a backup :-(

it's hard to 'repair' a shapefile, from what I see with QGIS there is
just one geometry in the shp file...
When I open the dbf file with libreoffice, it appears that there have
been 3(?) objects in it? There are three records in there.

Falling back to the command line:

ogrinfo -al fietstochten.shp

shows me:

      using driver `ESRI Shapefile' successful.

So it looks like something has damaged the dbf file?

I'm not aware of a way to repair such problems, I hope somebody else can
help you...
