When I find a neat static page on the web, such as a news article, I frequently save a local copy, as the web is pretty transient.  When I load a dolphin tab which lists such a saved page's HTML file, I get pop-up 'Open with' dialogs whenever it tries to generate a thumbnail for any html file that contains an iframe tag (which is now pointing to a local directory by reference.)

This is a rather annoying issue since it tries to make a thumbnail any time the html file is newly listed on screen, the mouse hovers over it, it is selected, etc.

By the way, may I humbly suggest that it shouldn't try to resolve any non-local external resources at all for thumbnails.

Reproducible: Always

Steps to Reproduce:
Using a sufficiently advanced browser that can save a Web Page, Complete (that is, not Konq) save a page that contains an iframe.  In dolphin settings, make sure thumbnails are enabled for HTML files.
View the directory that contains the saved html page (and associated page_files directory)

Actual Results:  
One or more pop-up Open with dialogs, with titles that contain part of the path to a file referenced in an iframe, and which list themselves as owned by kio_thumbmail (Yes, it says thumbMail, might want to fix that too.)
Open closing them, generally they pop-up again immediately.  Thankfully they are non-modal to the dolphin window.  
The thumbnail is of course not generated.

Expected Results:  
A simple thumbnail of the page.
