Version:           4.0.1 (KDE 4.0.1) (using 4.0.1 (KDE 4.0.1), Debian packages)

When I try to download a program from Sourceforge such as
    http://prdownloads.sourceforge.net/chmox/Chmox-0.3.dmg?download
I get a pop-up window, asking where to save the file.
Pressing "Cancel" makes Konqueror crash.
