Version: (using KDE KDE 3.5.4) Installed from: Ubuntu Packages Go to http://www.anime-ultime.net/V3/downloadselect.php clic on one of the title in the list, an "empty popup" appears. "Empty popup"= new konqueror window with "about:blank" title.
Unfortunately the site is gone and I can't retrieve a working version from archive.org. Did this problem stop for you after upgrading to a later version of konqueror?
Closing due to no response. Please reopen this bug if you can provide a copy of the site/page causing it.
