color depth for displaying images

[Thomas Schäffler <mailing ratzebaer de>]

Hi there,

I'm currently tagging my images in f-spot as it seems to be the best photo 
manager for my needs. 
I have one issue for now: 
Some images with smooth color gradients look ugly in f-spot (and in qqview 
also). This is not the case with some KDE apps (gwenview and digikam) and 
picasa. 
I have uploaded one extreme example to flickr:

It looks fine in firefox.
Can you explain this to me and is there a way to solve this?

I'm currently using SuSE 10.1 with KDE.

Thanks.
