Filemanager: Thumbnails view does not show thumb images

All,
 
when I open the Filemanager and navigate to a folder with images.
Then change the display-dropdown to "Thumbnails", the resulting images are not shown correctly.
It seems that _th_64 is appended to the image.
Unfortunately this is then not correctly picked up by the webdav servlet and a 404 is generated.
 
Is there a workaround for this, or will this be resolved in a next release.
 
This can be tested on the jahia demo site(below is the url that generates a 404) in the filemanager.

Kind regards,
 
Nicolas
