File saving dialog empty when trying to save file

[Johannes Postler]

I just scanned an image, cropped it and wanted to save it to my home folder. However, the file saving dialog does not show any of the file system structure. Therefore I cannot choose any location to save the image. I will attach a screenshot to demonstrate. Restarting simplescan did not help. I know that it used to work with this version of simple scan.
