Version: 1.3.1 (using KDE 4.1.2)
Installed from: Ubuntu Packages
from a feed I openend following URL in a tab:
this page contains a link to an image. Th image is shown correctly.
When navigating back it tries to load just "13290.html", not the complete URL, so the history seems broken.
Confirmed. Apparently the part used to show the image, pdf etc. isn't replaced by a HTML part when going back in the history. Your title describes another bug though.
SVN commit 876198 by osterfeld:
Store mimetype in history
Fixes back/forward in history when parts other than KHTMLPart are involved
