You are using the Wallbase.cc provider, correct?

Assuming that your problem is that wallpaper lists for Wallbase.cc aren't downloading then I think I see how to fix it (though not sure why it's actually an issue).  I'll fix it tomorrow night.

The wallpaper setter settings error is interesting, I'll have to look into it.

I think I see the cause of both issues.  I created two issues, shouldn't take much for me to fix them.

Actually I tied with NatGeo provider as well, and crashed too. This did not happened with Google search images but I've noticed that the "search results" were completely different from the search keyword and in the cache folder there were only images that comply with the defined dimensions in settings.

Try Pulse Beta 6, it should have the fixes for the two issues I noted above.  If the National Geographic issue persists please post the error message in a new thread.  If you have issues with Wallbase go ahead and post it here.
