problem with Gwenview

Hello When I use konqueror to open a director which contains images, everything seems fine: the images are displayed as thumbnails. However when I click on a jpg file, the file is displayed, but with the following message displayed: There was an error loading the module Gwenview Image Viewer. The diagnostics is: can't open the module I have gwenview and gwenview-kde3 installed. Is this message serious? Thanks Uwe Brauer
