Bug 128816

Version:            (using KDE KDE 3.5.3)
Installed from:    Debian testing/unstable Packages
OS:                Linux

This is probably not a very serious bug and is a bit tricky to reproduce. You probably should have a rather slow connection (or be very quick with your keyboard). But certainly it could be an issue for those with for example a modem or isdn; or when a web page is loading slowly. Here is how to reproduce this crash:

Open konqueror, go to for example www.google.com. Enter something (no matter what) in the search field. Press enter. By default you get the "Network transmission"-dialog, just press enter. And here comes the tricky part for those with a fast internet connection. After you have pressed enter on this dialog, but BEFORE the browser manages to load the page you requested, press enter once again. You should once again get the same "Network Transmission"-dialog. To be sure that the crash is reproduced correctly, wait for the page to load in the background of this dialog. Then press enter. When you do, konqueror crashes.

Here is the backtrace:

A similar crash (but with a bit different backtrace) can be reproduced in the following way. Open konqueror, go to www.google.com, enter a search term, then begin to press enter rapidly (you should get several "Network transmission"-dialogs, but just continue pressing enter). Do this until konqueror crashes, it shouldn't take a long time.

I'm aware of that this is more like a way of "abusing" the software rather than "using" it, but it shouldn't lead to crash at least ;)
