Version:            (using KDE KDE 3.5.7)
Installed from:    Debian testing/unstable Packages

Reported in Debian BTS at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=425880

I experience frequent konqueror crashes when I Shift+Click on a URL leading to
a PDF article. This happens on the URLs, which will autoload in few seconds. I
personally think that the crash occurs when I click at exactly the same time
that JavaScript or some similar mechanism attempts to open that PDF in
the konqueror automatically. This works with PDF links offered by the majority
of research journals, so the test cases should be easy to find. I am not sure
I can provide a good working sample link as a lot of them require
subscription. Here are some examples anyway:
